This suit appears to be almost identical to the one worn by Keaton in Batman Returns, albeit with smaller ears.
What happened to rumors of a suit with a more lithe, Year One appearance, with actual pouches on the utility belt and treads on the boots? I thought that, given the success of the fabric Spidey costume, and the desire on the part of the WB and Nolan to differentiate this film from the previous installments, that they would have tried to re-interpret the look of the character, with a more realistic, less rigid costume.
Given the script's reliance on martial arts and acrobatics, I fail to see how this outfit, which is bunching up awkwardly under Bale's armpits even while he's just crouching, is going to look in combat. It seems Bats may still be unable to convincingly turn his head.
That said, Bale looks sexy and dangerous as Wayne, something which none of the other actors in the part were able to pull off.
