Christian Bale sported a podgy, balding look in the film.
When Robert De Niro met the entire cast, he asked director David O Russell who the overweight guy was.
"After he met everybody he said, 'Who is that guy?' I said, 'You just shook his hand, that's Christian Bale.' He said, 'No, that guy.' I said, 'Yeah, that's Christian Bale.'" Huffingtonpost.com quoted David O Russell.
The crime drama also featured Jennifer Lawrence, Bradley Cooper, Amy Adams and Jeremy Renner.
