Digital capture -- 17 megapixels' worth, shot with the Canon EOS-1Ds Mark II -- helped close the deal with Jackman. Muller just fired up his laptop and showed the actor, who plays the film's Wolverine character, what he had already produced. "When you can show the director and the cast on the spot that the pictures you've been doing are good, they're much more open to working with you," says Muller, who has since posterized superheros for Spider-Man: The Last Stand, the Fantastic Four: Rise of the Silver Surfer, and Robert Downey Jr.'s new Iron Man. "It becomes a very organic, collaborative experience." This doesn't change the time constraints, however. "I've got to be able to light and shoot someone in less than five minutes," he says. "Time is money, maybe a million dollars a day on a big movie, and the poster photographer is low-priority."
