2009, the Academy of Motion Picture Arts and Sciences expanded on a tradition that had existed since 1927. It increased the number of potential Best Picture nominations from the usual five to a potential maximum of 10. It was a move to inject more blockbusters into the Oscar mix and to give movies like Avatar, Inception, and Toy Story 3 the recognition of Best Picture that they deserved. But in essence, this was The Dark Knight rule. This 2008 film, the most incredible superhero movie ever made, was nominated for eight Academy Awards and won two (Best Supporting Actor – Heath Ledger, Best Achievement in Sound Editing).
