As Oscar tradition goes, the presenter of Best Female Actor is the previous years Best Actor winner. And this year that would be Casey Affleck.
Affleck won the award for Best Actor last year for Manchester by the Sea, and Room star Brie Larson, who won the Best Actress award in 2016, refused to clap for Affleck when she presented him with the trophy last year.
Back in 2010, two women came forward to accuse Affleck of sexual harassment on the set of 2010's I'm Still Here, filing civil suits against the actor. Affleck denied the charges and settled the cases out of court.
So, in light of the #MeToo and #TimesUp movements Affleck has decided getting up on that stage wouldn't gov over so well.
