And in keeping with the "theme of the day": inclusion rider.  The idea, which is gaining traction (thanks largely to Frances McDormand's Oscar acceptance speech), began with a woman named Stacy Smith.

The idea for inclusion riders was developed by Stacy Smith, founder and director of the University of Southern California’s Annenberg Inclusion Initiative, and drafted with Kalpana Kotagal of the law firm Cohen Milstein and the producer and actor Fanshen Cox DiGiovanni. Smith spoke about it in a TED talk in 2016, and the idea has gained ground ever since.

It's fairly simple in design but, naturally, allows for deviation in cases of historical representation, etc.  It states:

The purpose of the inclusion rider is “to counter biases on the casting, auditioning, interviewing and hiring process. For on-screen roles that are supporting and minor in nature, they have to be filled with norms that reflect the world in which we live,” Smith said. That means, for a contemporary drama, approximately 50 percent women, 50 percent minority, 20 percent people with disabilities and five percent LGBTQ, she added. Historical dramas where this formula doesn’t make sense would be exempt.

Some people aren't happy, claiming it calls for "quotas" and such.  And what if it does?  The bottom line is that it's a rider to a contract signed and negotiated between talent representation and the studio.  Not a bad idea ... for starters.
