“Chris [Nolan] has a very astute eye,” says Nick Davis, the film's visual effects supervisor. “It was important for the visual effects to look as though they were shot on set. He didn’t want the film to take on a gimmicky visual-effects look.” In keeping with that philosophy, Nolan shot footage for the major visual-effects sequences with IMAX cameras, making The Dark Knight the first feature film shown in IMAX that wasn't originally shot in 35mm.
