Black Panther actor Michael B Jordan has pledged to insert an “inclusion rider” clause into his future movie contracts.

At the Oscars on Sunday night (March 4), Three Billboards Outside Ebbing, Missouri star Frances McDormand used her Best Actress acceptance speech to call for greater equality in the film industry and helped shine a spotlight on the little-known diversity clause.

“We all have stories to tell and we need finance,” McDormand said. “Don’t talk to us about it at the parties tonight. Invite us into your office in a couple days – or you can come to ours, whichever suits you best – and we’ll tell you all about them. I have two words to leave with you tonight, ladies and gentlemen: ‘inclusion rider’.”

An inclusion rider, McDormand later explained to the press backstage, “means that you can ask for and/or demand at least 50% diversity, not only in casting but also [in] the crew.”
