Gender diversity in the film industry
This article is originally published at https://www.mango-solutions.com
The year 2017 has completely turned the film industry upside down. The allegations of harassment and sexual assault against Harvey Weinstein have raised the issue of sexism and misogyny in this industry to the eyes of the general public. In addition, it has helped raise awareness of the poor gender diversity and under-representation of women in Hollywood. One of the main problems posed by the low presence of women behind the camera is that this is then reflected in the fictional characters on screen: lots of movies portray women in an incomplete, stereotyped and biased way.
This post focuses on some key behind-the-camera roles to measure the evolution of gender diversity in the last decade – from 2007 until 2017. The roles I studied were: directors, writers, producers, sound teams, music teams, art teams, makeup teams and costume teams.
The whole code to reproduce the following results is available on GitHub
.
Data frame creation – Web scraping
What I needed first was a list which gathered the names connected to film job roles for 50 movies. For each year between 2007 and 2017, I gathered the information about the 50 most profitable movies of the year from the IMDb website.
As a first step, I built data frames which contained the titles of these movies, their gross profit and their IMDb crew links – which shows the names and roles of the whole movie crew. The following code is aimed at building the corresponding data frame for the 50 most profitable movies of 2017.
# IMDB TOP US GROSSING 2017: 50 MORE PROFITABLE MOVIES OF 2017 -------------
url <- "https://www.imdb.com/search/title?release_date=2017-01-01,2017-12-31&sort=boxoffice_gross_us,desc"
page <- read_html(url)
# Movies details
movie_nodes <- html_nodes(page, '.lister-item-header a')
movie_link <- sapply(html_attrs(movie_nodes),`[[`,'href')
movie_link <- paste0("http://www.imdb.com", movie_link)
movie_crewlink <- gsub("[?]", "fullcredits?", movie_link) #Full crew links
movie_name <- html_text(movie_nodes)
movie_year <- rep(2017, 50)
movie_gross <- html_nodes(page, '.sort-num_votes-visible span:nth-child(5)') %>%
html_text()
# CREATE DATAFRAME: TOP 2017 ----------------------------------------------
top_2017 <- data.frame(movie_name, movie_year, movie_gross, movie_crewlink, stringsAsFactors = FALSE)
Let’s have a look at the top_2017
data frame:
## movie_name movie_year movie_gross
## 1 Star Wars: Episode VIII - The Last Jedi 2017 $620.18M
## 2 Beauty and the Beast 2017 $504.01M
## 3 Wonder Woman 2017 $412.56M
## 4 Jumanji: Welcome to the Jungle 2017 $404.26M
## 5 Guardians of the Galaxy: Vol. 2 2017 $389.81M
## 6 Spider-Man Homecoming 2017 $334.20M
## movie_crewlink
## 1 http://www.imdb.com/title/tt2527336/fullcredits?ref_=adv_li_tt
## 2 http://www.imdb.com/title/tt2771200/fullcredits?ref_=adv_li_tt
## 3 http://www.imdb.com/title/tt0451279/fullcredits?ref_=adv_li_tt
## 4 http://www.imdb.com/title/tt2283362/fullcredits?ref_=adv_li_tt
## 5 http://www.imdb.com/title/tt3896198/fullcredits?ref_=adv_li_tt
## 6 http://www.imdb.com/title/tt2250912/fullcredits?ref_=adv_li_tt
I adapted the previous code in order to build equivalent data frames for the past 10 years. I then had 11 data frames: top2017
, top2016
, …, top2007
, which gathered the names, years, gross profit and crew links of the 50 most profitable movies of each year.
I combined these 11 data frames into one data frame called top_movies
.
List creation – Web scraping
After that, I had a data frame with 550 rows, and I next needed to build a list which gathered:
- the years from 2007 to 2017
- for each year, the names of the top 50 grossing movies corresponding
- for each movie, the names of the people whose job was included in one of the categories I listed above (director, writer, costume teams)
In order to build this list, I navigated through all the IMDb full crew web pages stored in our top_movies
data frame, and did some web scraping again to gather the information listed above.
movies_list <- list()
for (r in seq_len(nrow(top_movies))) {
# FOCUS ON EACH MOVIE -----------------------------------------------------------------
movie_name <- top_movies[r, "movie_name"]
movie_year <- as.character(top_movies[r, "movie_year"])
page <- read_html(as.character(top_movies[r, "movie_crewlink"]))
# GATHER THE CREW NAMES FOR THIS MOVIE ------------------------------------------------
movie_allcrew <- html_nodes(page, '.name , .dataHeaderWithBorder') %>%
html_text()
movie_allcrew <- gsub("[\n]", "", movie_allcrew) %>%
trimws() #Remove white spaces
# SPLIT THE CREW NAMES BY CATEGORY ----------------------------------------------------
movie_categories <- html_nodes(page, '.dataHeaderWithBorder') %>%
html_text()
movie_categories <- gsub("[\n]", "", movie_categories) %>%
trimws() #Remove white spaces
## MUSIC DEPARTMENT -------------------------------------------------------------------
movie_music <- c()
for (i in 1:(length(movie_allcrew)-1)){
if (grepl("Music by", movie_allcrew[i])){
j <- 1
while (! grepl(movie_allcrew[i], movie_categories[j])){
j <- j+1
}
k <- i+1
while (! grepl(movie_categories[j+1], movie_allcrew[k])){
movie_music <- c(movie_music, movie_allcrew[k])
k <- k+1
}
}
}
for (i in 1:(length(movie_allcrew)-1)){
if (grepl("Music Department", movie_allcrew[i])){
j <- 1
while (! grepl(movie_allcrew[i], movie_categories[j])){
j <- j+1
}
k <- i+1
while (! grepl(movie_categories[j+1], movie_allcrew[k])){
movie_music <- c(movie_music, movie_allcrew[k])
k <- k+1
}
}
}
if (length(movie_music) == 0){
movie_music <- c("")
}
## IDEM FOR OTHER CATEGORIES ---------------------------------------------------------
## MOVIE_INFO CONTAINS THE MOVIE CREW NAMES ORDERED BY CATEGORY ----------------------
movie_info <- list()
movie_info$directors <- movie_directors
movie_info$writers <- movie_writers
movie_info$producers <- movie_producers
movie_info$sound <- movie_sound
movie_info$music <- movie_music
movie_info$art <- movie_art
movie_info$makeup <- movie_makeup
movie_info$costume <- movie_costume
## MOVIES_LIST GATHERS THE INFORMATION FOR EVERY YEAR AND EVERY MOVIE ----------------
movies_list[[movie_year]][[movie_name]] <- movie_info
}
Here are some of the names I collected:
## - Star Wars VIII 2017, Director:
## Rian Johnson
## - Sweeney Todd 2007, Costume team:
## Colleen Atwood, Natasha Bailey, Sean Barrett, Emma Brown, Charlotte Child, Charlie Copson, Steve Gell, Liberty Kelly, Colleen Kelsall, Linda Lashley, Rachel Lilley, Cavita Luchmun, Ann Maskrey, Ciara McArdle, Sarah Moore, Jacqueline Mulligan, Adam Roach, Sunny Rowley, Jessica Scott-Reed, Marcia Smith, Sophia Spink, Nancy Thompson, Suzi Turnbull, Dominic Young, Deborah Ambrosino, David Bethell, Mariana Bujoi, Mauricio Carneiro, Sacha Chandisingh, Lisa Robinson
Gender determination
All of the names I needed to measure the gender diversity of were now gathered in the list movies_list
. Then, I had to determine the gender of almost 275,000 names. This is what the R package GenderizeR does: “The genderizeR package uses genderize.io API to predict gender from first names”. At the moment, the genderize.io database contains 216286 distinct names across 79 countries and 89 languages. The data is collected from social networks from all over the world, which ensure the diversity of origins.
However, I am aware that determining genders based on names is not an ideal solution: some names are unisex, some people do not recognise themselves as male or female, and some transitioning transgender people still have their former name. But this solution was the only option I had, and as I worked on about 275,000 names, I assumed that the error induced by the cases listed above was not going to have a big impact on my results.
With this in mind, I used the GenderizeR package and applied its main function on the lists of names I gathered earlier in movies_list
. The function genderizeAPI
checks if the names tested are included in the genderize.io database and returns:
- the gender associated with the first name tested
- the counts of this first name in database
- the probability of gender given the first name tested.
The attribute I was interested in was obviously the first one, the gender associated with the first name tested.
The aim was to focus on every category of jobs, and to count the number of males and females by category, film and year. With the script below, here is the information I added to each object movies_list$year$film
:
- the number of male directors
- the number of female directors
- the number of male producers
- the number of female producers
- the number of males in costume team
- the number of females in costume team
The following code shows how I determined the gender of the directors’ names for every film in the movie_list
. The code is similar for all the other categories.
# for each year
for (y in seq_along(movies_list)){
# for each movie
for (i in seq_along(movies_list[[y]])){
# Genderize directors -----------------------------------------------------
directors <- movies_list[[y]][[i]]$directors
if (directors == ""){
directors_gender <- list()
directors_gender$male <- 0
directors_gender$female <- 0
movies_list[[y]][[i]]$directors_gender <- directors_gender
}
else{
# Split the firstnames and the lastnames
# Keep the firstnames
directors <- strsplit(directors, " ")
l <- c()
for (j in seq_along(directors)){
l <- c(l, directors[[j]][1])
}
directors <- l
movie_directors_male <- 0
movie_directors_female <- 0
# Genderize every firstname and count the number of males and females
for (p in seq_along(directors)){
directors_gender <- genderizeAPI(x = directors[p], apikey = "233b284134ae754d9fc56717fec4164e")
gender <- directors_gender$response$gender
if (length(gender)>0 && gender == "male"){
movie_directors_male <- movie_directors_male + 1
}
if (length(gender)>0 && gender == "female"){
movie_directors_female <- movie_directors_female + 1
}
}
# Put the number of males and females in movies_list
directors_gender <- list()
directors_gender$male <- movie_directors_male
directors_gender$female <- movie_directors_female
movies_list[[y]][[i]]$directors_gender <- directors_gender
}
# Idem for the 7 other categories -----------------------------------------------------
}
}
Here are some examples of the number of male and female names I collected:
## - Star Wars VIII 2017
## Number of male directors: 1
## Number of female directors: 0
## - Sweeney Todd 2007
## Number of male in costume team: 9
## Number of female in costume team: 20
Percentages calculation
Once I had all the gender information listed above, the next step was to calculate percentages by year. I then went through the whole list movies_list
and created a data frame called percentages
which gathered the percentages of women in each job category for each year.
Let’s have a look at the percentages
data frame:
## year women_directors women_writers women_producers women_sound

Visualisation – gender diversity in 2017
I was then able to visualise these percentages. For example, here is the code I used to visualise the gender diversity in 2017.
# Formating our dataframe
percentages_t <- data.frame(t(percentages), stringsAsFactors = FALSE)
colnames(percentages_t) <- percentages_t[1, ]
percentages_t <- percentages_t[-1, ]
rownames(percentages_t) <- c("directors", "writers", "producers", "sound", "music", "art", "makeup", "costume")
# Ploting our barplot
percentages_2017 <- percentages_t$`2017`
y <- as.matrix(percentages_2017)
p <- ggplot(percentages_t, aes(x = rownames(percentages_t),
y = percentages_2017,
fill = rownames(percentages_t))) +
geom_bar(stat = "identity") +
coord_flip() + # Horizontal bar plot
geom_text(aes(label=format(y, digits = 2)), hjust=-0.1, size=3.5) + # pecentages next to bars
theme(axis.text.y=element_blank(),
axis.ticks.y=element_blank(),
axis.title.y=element_blank(),
legend.title=element_blank(),
plot.title = element_text(hjust = 0.5)) + # center the title
labs(title = "Percentages of women in the film industry in 2017") +
guides(fill = guide_legend(reverse=TRUE)) + # reverse the order of the legend
scale_fill_manual(values = brewer.pal(8, "Spectral")) # palette used to fill the bars and legend boxs
As we can see, in 2017, the behind-the-camera roles of both directors and writers show the most limited women occupation: less than 10% for writers and less than 4% for directors. This is really worrying considering that these are key roles which determine the way women are portrayed in front of the camera. Some studies have already shown that the more these roles are diversified in terms of gender, the more gender diversity is shown on screen.
Let’s go back to our barplot. Women are also under-represented in sound teams (14%), music teams (22.5%), producer roles (23%) and art teams (27%). The only jobs which seem open to women are the stereotyped female jobs of make-up artists and costume designers, among which almost 70% of the roles are taken by women.
Visualisation – gender diversity evolution through the last decade
Even if the 2017 results are not exciting, I wanted to know whether there had been an improvement through the last decade. The evolution I managed to visualise is as follows.
# From wide to long dataframe
colnames(percentages) <- c("year", "directors", "writers","producers", "sound",
"music", "art", "makeup", "costume")
percentages_long <- percentages %>%
gather(key = category, value = percentage, -year)
percentages_long$year <- ymd(percentages_long$year, truncated = 2L) # year as date
# line plot
evolution_10 <- ggplot(percentages_long, aes(x = year,
y = percentage,
group = category,
colour = category)) +
geom_line(size = 2) +
theme(panel.grid.minor.x = element_blank(),
plot.title = element_text(hjust = 0.5)) + # center the title
scale_x_date(date_breaks = "1 year", date_labels = "%Y") +
scale_color_manual(values = brewer.pal(8, "Set1")) +
labs(title = "Percentages of women in the film industry from 2007 to 2017",
x = "",
y = "Percentages")
The first thing I noticed is that the representativeness gap between the roles of make-up artists and costume designers and the other ones has not decreased in a flagrant way since 2007.
In addition, the roles that women are really under-represented – directors, writers and jobs related to sound, no improvement has been achieved.
If we focus on directors, we do not see any trend. Figures vary depending on the year we consider. For example in 2010, we notice that there are not any female directors among the 50 most profitable movies, and for other years it never goes beyond 7.5%. What is interesting for the role of director, the best levels of female representation were reached in 2008 and 2009. After these years the number of female directors has declined and never reached more than 6%. The percentage of women directors reached in 2017 is practically the same as the percentage reached in 2007.
We then notice an evenness in the number of female sound teams and writers: women consistently represent around 10% of writers and 15% of sound teams in the last decade. But there is no sign of improvement.
Only a slight improvement of 3-5% is notable among producers, music and art teams. But nothing astonishing.
Visualisation – gender diversity forecasting in 2018
The last step of our study was to forecast, at a basic level, these percentages for 2018. I used the forecast package and its function forecast
, and then applied it to the data I collected between 2007 and 2017, in order to get this prediction:
# Time series
ts <- ts(percentages, start = 2007, end = 2017, frequency = 1)
# Auto forecast directors 2018
arma_fit_director <- auto.arima(ts[ ,2])
arma_forecast_director <- forecast(arma_fit_director, h = 1)
dir_2018 <- arma_forecast_director$fitted[1] # value predicted
# Idem for writers, producers, sound, music, art, makeup and costume
# Create a data frame for 2018 fitted values
percentages_2018 <- data.frame(year = ymd(2018, truncated = 2L),
women_directors = dir_2018,
women_writers = writ_2018,
women_producers = prod_2018,
women_sound = sound_2018,
women_music = music_2018,
women_art = art_2018,
women_makeup = makeup_2018,
women_costume = costu_2018,
stringsAsFactors = FALSE)
# Values from 2007 to 2017 + 2018 fitted values
percentages_fitted_2018 <- bind_rows(percentages, percentages_2018)
# From wide to long dataframe
colnames(percentages_fitted_2018) <- c("year", "directors", "writers","producers", "sound",
"music", "art", "makeup", "costume")
percentages_long_f2018 <- percentages_fitted_2018 %>%
gather(key = category, value = percentage, -year)
percentages_long_f2018$year <- ymd(percentages_long_f2018$year, truncated = 2L) # year as date
# Forecast plot for 2018
forecast_2018 <- ggplot(percentages_long_f2018, aes(x = year,
y = percentage,
group = category,
colour = category)) +
geom_line(size = 2)+
theme(panel.grid.minor.x = element_blank(),
plot.title = element_text(hjust = 0.5)) + # center the title
scale_x_date(date_breaks = "1 year", date_labels = "%Y") +
scale_color_manual(values = brewer.pal(8, "Set1")) +
labs(title = "Percentages of women in the film industry from 2007 to 2017\n Fitted values for 2018",
x = "",
y = "Percentages")
The predicted values I got for 2018 are approximately the same as the ones I calculated for 2017. However, it is a basic forecast, and it does not take into consideration the upheaval which happened in the film industry in 2017. This will surely have an impact on the gender diversity in the film industry. But to what extent? Has general awareness been sufficiently increased to truly achieve change?
In any case, I sincerely hope that our forecasting is wrong and that a constant improvement will be seen in the next couple of years, so that female characters on cinema screens will become more interesting and complex.
