The Academy of Motion Picture Arts and Sciences has overhauled rules around campaigning for Oscars after incidents involving Andrea Riseborough, Jerry Bruckheimer and Michelle Yeoh

The Academy of Motion Picture Arts and Sciences has announced its “most significant overhaul” of rules around campaigning for Oscars, fresh after Andrea Riseborough’s controversial nomination for best actress.

The changes and clarifications come after several incidents were flagged as possibly breaking the rules around campaigning for nominations at this year’s Academy Awards. These included Riseborough’s nomination for her performance in To Leslie, after an aggressive guerrilla campaign that saw actors including Kate Winslet, Amy Adams and Gwyneth Paltrow endorse the low-budget indie film. The British actor had not been considered a contender for a nomination, with some suggesting her inclusion had come at the expense of Black actors.
