Munn was one of six women who came forward with accusations against Ratner, as initially published in The Times. The "X-Men: Apocalypse" star claimed the director once masturbated in front of her and made sexually aggressive comments to her in public.
"I want Warner Bros. to sever all ties and relationships with Brett Ratner," the actor said in a new interview with The Los Angeles Times.
Ratner's attorney, Martin Singer, has denied the allegations against his client.
He was said to no longer be involved as a producer on the film adaptation of "The Goldfinch," and RatPac will no longer hold office space on the Warner Bros lot in Hollywood.
Gal Gadot has also confirmed that Ratner would not be involved with the sequel to "Wonder Woman".
