(Howard and Zimmer), and Best Special Effects (Corbould, Nick Davis, Paul J. Franklin, Timothy Webber). Before The Dark Knights release, film industry discourse focused on Ledger potentially earning an Academy Award nomination at the 81st Academy Awards in 2009, making him only the seventh person to be nominated posthumously, and if the decision would be influenced by his passing or performance. Genre films such as those based on comic books were also generally ignored by Academy voters. Even so, Ledger was considered a favorite to earn the award based on praise from critic groups and his posthumous Golden Globe award. Ledger won the Academy Award for Best Supporting Actor, making him only the second performer to win an award posthumously (after Peter Finch in 1977), and The Dark Knight the first comic book adaptation to win an Academy acting award. The Dark Knight also won an award for Best Sound Editing (King), and received six nominations for Best Art Direction (Crowley and Peter Lando), Best Cinematography (Pfister), Best Film Editing (Smith), Best Makeup (Caglione Jr. and O'Sullivan), Best Sound Mixing (Hirschberg, Rizzo, and Ed Novick), and Best Visual Effects (Davis, Corbould, Webber, and Franklin). Despite the success of The Dark Knight, the lack of a Best Picture nomination was criticized and described as a "snub" by some publications. The response was seen as the culmination of several years of criticism toward the Academy ignoring high-performing, broadly popular films. The backlash was such that, for the 82nd Academy Awards awards in 2010, the Academy increased the limit for Best Picture nominees from five to ten, a change known as "The Dark Knight Rule". It allowed for more broadly popular but "respected" films to be nominated, including District 9, The Blind Side, Avatar, and Up, the first animated film to be nominated in two decades. This change is seen as responsible for the first Best Picture nomination of a comic book adaptation, Black Panther (2018). Even so, The Hollwood Reporter argued the Academy mistook the appeals to recognize important, "generation-defining" genre films with just nominating more films. Other releases Home media The Dark Knight was released on DVD and Blu-ray in December 2008. The release has a slipcover box-art that revealed a "Jokerized" version underneath, and contains featurettes on Batman's equipment, the psychology used in the film, six episodes of the fictional news program Gotham Tonight, and a gallery of concept art,
