There are three different IMAX theater locations in the Valley and only one of them is showing I Am Legend with a special-feature preview of the upcoming The Dark Knight movie. AMC Deer Valley 30 with IMAX featured the clip, which was first six minutes of the sequel to Batman Begins. The new film opens July 18. In it Bruce Wayne/Batman continues to clean up the corrupt and criminal streets of Gotham City and faces two new villains — Two-Face (played by Aaron Eckhart) and his greatest enemy The Joker (played by Heath Ledger). Four major action sequences in the movie were filmed with IMAX cameras, one of them being the introduction of the Joker at the start of the movie. Click here for a detailed description of the preview. I won’t get into particulars here, but I will say the clip gives me no doubt that The Dark Knight will be a amazing film and that Heath Ledger will rule the role of the Joker.
