Christian Bale almost quit his role as Batman because of the tight costume.
The 38-year-old actor - who tackles the superhero and his alter ego Bruce Wayne for the third time in forthcoming movie 'The Dark Knight Rises' - was so "claustrophobic" when he donned the iconic suit for the first time in 'Batman Begins', he thought director Christopher Nolan should recast the part.
He said: "I felt like they should recast. I really did because it was so claustrophobic that I didn't feel like I could breathe. I felt, 'They've made a mistake and I can't do this.' "
However, Christian managed to calm himself down and overcome his fear of the suit.
He added to 'Access Hollywood': "I took some time and breathed deeply and asked to be left alone for 15, 20 minutes and just sat with it and eventually got used to it."
Anne Hathaway has joined the cast of 'The Dark Knight Rises' and Christian thinks she has done a "wonderful job" portraying Catwoman in the way the filmmakers envisaged the character.
He said: "She did a wonderful job. She really trained so hard for it. She managed to find a place for herself where she could make this version of Catwoman work within Chris Nolan's world of Batman.
"I remember when she first read for it, I turned to Chris and I said,' I think that's what you're looking for,' I could see that through the costume a Catwoman. She was able to overcome that and still show the character... she was superb."
