Since producer Harvey Weinstein was expelled from the Academy in October, following allegations of sexual misconduct that Weinstein has denied, the group received criticism by some in Hollywood for not taking similar action with Polanski.
No additional information was immediately available about the pair being expelled from the Academy.
Separately Thursday, members of the American Advertising Federation’s (AFF), a trade organization that recognizes professional achievements in the advertising industry, voted to rescind Cosby’s induction into the Advertising Hall of Fame. The group also rescinded Cosby’s President’s Award, which was presented to him at the time of his 2011 induction.
According to the AFF, this is the first time members have voted to rescind an induction or award in its 69-year-history.
CNN has reached out to Cosby’s representatives for comment.
