The score for The Dark Knight was composed by Hans Zimmer and James Newton Howard. A soundtrack was released on July 15, 2008 by Warner Records. A second, "Special Edition" soundtrack was also released. Both albums had the same track listing; aside from a different cover the "Special Edition" also included a foldout poster, a photo of the Joker, and three trading cards. But later, on December 9, 2008, Warner Records released a 2 Disc COLLECTORS EDITION, with a 40 page hardbound book, 50 minutes of unreleased music from the movie, and 4 unreleased remixes by The Crystal Method, Paul Van Dyk, Mel Wesson and Ryeland Allison.
