Its become a running gag with all of the Batman films that nobody who plays Batman actually likes wearing that damn suit, unless theyre standing under an air conditioner all day striking poses. And while the suits did indeed improve from film to film in terms of comfort and ease of use, Christian Bales favorite phrase to use about the Batsuit was still its hot, its sweaty and its giving me a headache a phrase that, according to Art and Making of the Dark Knight Trilogy, members of the crew adopted and put on T-shirts. Bale, for his part, tried to use his crankiness and discomfort in the suit to his advantage, feeding his constant headaches into Batmans animal aggression.
