Bill Cosby and Roman Polanski have been expelled from the US Academy of Motion Picture Arts and Sciences.
The prestigious organisation - which runs the Oscars - made the announcement on Thursday.
TV star Cosby was convicted of sexual assault last month.
Director Polanski admitted statutory rape of a 13 year-old in 1977.
Producer Harvey Weinstein was kicked out last year, following numerous allegations of sexual assault.
The academy said its board members made the latest decision after a vote on Tuesday.
