The first six minutes of The Dark Knight, the follow-up to Batman Begins, will play as a preview in IMAX theaters showing Will Smith's I Am Legend (hitting screens Dec. 14). The opening sequence concerns a bank robbery by clown-masked henchmen, and leads up to the first look at Heath Ledger's Joker. "Seeing this extraordinary face, eight stories high.... You can smell his breath," director Chris Nolan tells the Reporter. "It's a creepy moment, as it should be" - especially since the Joker is known to eat lots of onions.
