“Extra’s” AJ Calloway caught up with “American Hustle” stars Jennifer Lawrence, Christian Bale, and Bradley Cooper as they promoted the upcoming film.

Christian talked about gaining over 40 pounds for the role, saying that he was no longer Batman, but “Fatman,” before returning to his normal weight after filming. Jennifer talked about her annoyance at how quickly Christian was able to drop the pounds.

Bradley Cooper chatted about the inspiration behind his wild hairdo in the movie, and whether he would show up to the awards shows this season in his full “American Hustle” getup.
