In a major shift for Oscar voting protocol, the Academy of Motion Picture Arts and Sciences has announced that members will now be required to confirm they've watched all nominated films in a category before being allowed to vote in that race.

The Academy has revealed it will change Oscars rules to require members to have seen the nominated films before voting in all competitive Academy Awards categories.

The Academy of Motion Picture Arts and Sciences is set to clamp down on shirkers within the voting body for the Oscars. The most headline-grabbing of recently announced new regulations concerns a requirement for members to have seen every film nominated in any category for which they wish to vote.
