Mel Gibson’s The Passion of the Christ has raked in an astounding $370.3 million at the box office, and now it’s going to give the DVD market a try. The DVD and VHS copies come out on August 31 but pre-sales are already 20 percent ahead of projections. Part of the boost comes from special packs of 50 DVDs Fox is marketing to churches, a move from the World Wide Pictures bag of tricks (now there’s a phrase you don’t get to write very often!). Despite predictions that The Passion will sell 20 million copies, experts expect Shrek 2 to outsell it.
