Mahershala Ali is opening up about his award-winning acting career and the limits he sets when accepting roles.

The 46-year-old actor, who has starred in "The Curious Case of Benjamin Button," "House of Cards" and "Moonlight," got candid on Common's "Mind Power Mixtape" podcast about his personal and professional life.

When speaking about his role as Tizzy Weathers in "The Curious Case of Benjamin Button" opposite Taraji P. Henson, he revealed why he refused to film a sex scene with the actress. It turns out it was a request he made before he ever made it to set.

"So my old agent called me and said, ‘Mahershala, you got the part,'" Ali recalled via Page Six. "And I said, 'There’s just one thing...There is that one sex scene where they kiss...If there’s a sex scene, I can’t do it.'"

Director David Fincher supported his request, resulting in the actor and Henson kissing in a scene.

"It wasn't clear if [Fincher] was trying to have like some bumping and grinding...which I doube he was," Ali continued. "But for me even...at that time, 15 years ago, I was still like, 'Ok, I can only go up to this point,' just because of -- just trying to hold a space of respect for my religion."

After his win, Ali addressed the controversy backstage at the awards show.
