Apparently, The Dark Knight director Christopher Nolan, a huge BD supporter, had persuaded the studio to break new ground in this arena, which would likely benefit his film's Oscar chances greatly.
"The Blu-ray version is vastly superior to DVD," Nolan said. "You can actually see the things we did in Imax, and it will give Academy members the best possible chance to see what we did technically."
With its incredible box office success ($523 million domestic gross) and critical success (95% "Fresh" rating on Rotten Tomatoes), The Dark Knight could be a rare blockbuster that garners Academy consideration, and BD screeners of the film will only enhance its chances.
Other studios have been considering offering 1080p screeners to Oscar voters as well. Sony might offer a Blu-Ray screener for its Will Smith drama Seven Pounds, but it isn't clear if a BD screener could be made available in time to ship to voters, since the film opens on December 19.
The Dark Knight was released July 18th, 2008 and stars Christian Bale, Heath Ledger, Aaron Eckhart, Michael Caine, Maggie Gyllenhaal, Gary Oldman, Morgan Freeman, Monique Gabriela Curnen. The film is directed by Christopher Nolan.
