We know that the film industry has visible diversity problems, from directing to acting. We can point to the lack of racial diversity among the Oscar acting nominees as a glaring problem, but less obviously, behind-the-camera craft roles like sound and editing suffer from both subtle and overt racism.
Variety recently ran a cover story about what they've termed #ArtisansSoWhite, the white male dominance of the technical side of the film industry. Their article includes a number of troubling anecdotes, not just of racial imbalance but outright hostility. One visual effects supervisor even recounted having his skills questioned by someone who asserted he was a diversity hire.
This has implications for mentoring opportunities and the type of work available to non-white artisans; one interviewee noticed that she had worked overwhelmingly on films about African-Americans, exclusively slotted into those films by producers.
Variety's exposé is long, disconcerting, and worth a read for those interested in where the industry needs to improve.
