Batman 3 MAY get a post conversion of 3D, because WB is going 3D crazy, but this will not effect how Nolan and Pfisher shoot the film. IMAX? Yes, most likely for some scene's but definitely not the entire film. However I think it would be great if he could talk WB into letting him shoot the majority of the film in 65mm, some in IMAX, and for some select scenes if needed, 35mm film. I don't see shooting in 35mm to be special, because 90% of all Hollywood movies are shot on 35mm. However, as Nolan stated it is still the highest quality practical format to shoot on.
