When Frances McDormand used the closing of her best actress acceptance speech at the Academy Awards on Sunday to promote inclusion riders, a contract clause for actors that would require filmmakers to meet diversity bench marks in their cast and crew, she jolted the idea into national consciousness.

It raised the question of when the first A-list star would insist on one in his or her own contract.

That hasn’t happened. But Wednesday, actor Michael B. Jordan took a step, announcing that his company, Outlier Society Productions, would adopt the rider for its projects.

The announcement made him the first major actor to publicly adopt the idea since McDormand’s speech. But Jordan, the villain of “Black Panther” and the hero of “Creed,” gave no indication that he would require the rider for the blockbuster movies he performs in.

Instead, Jordan pledged that Outlier would meet certain diversity requirements, though it was not known what specific requirements the company would hold itself to.

“I’ve been privileged to work with powerful woman & persons of color throughout my career, and it’s Outlier’s mission to continue to create for talented individuals going forward,” he wrote on Instagram.

Outlier, founded in 2016, is producing “Raising Dion,” a 10-episode drama about a single mother raising a superhero. Jordan, one of the show’s executive producers, will act in the series, which is due on Netflix in 2019.

The company is developing a reboot of “The Thomas Crown Affair,” and Jordan will make his directorial debut with an adaptation of “The Stars Beneath Our Feet.” It was not known whether the inclusion rider would apply to those projects and others underway.

As explained by Stacy Smith, who researches gender equality in film and television at the University of Southern California, inclusion riders would increase the representation of women, people of color and members of LGBT communities on screen and behind the camera. As an example, it might require the cast be 50 percent female, 40 percent underrepresented ethnic groups, 20 percent people with disabilities and 5 percent LGBT people.

On Thursday, Smith said she was thrilled that someone “at the heartbeat of culture” would offer his support. Other actors have reached out through representatives “on a fact-finding journey” but Jordan was the first to go public with his support of the idea, she said.

“This is a win on every level,” she said.
