Johnny Depp is "fascinated" by gangsters. The Hollywood hunk, who plays notorious bank robber John Dillinger in his new movie "Public Enemies," was drawn to the role because of his interest in the charismatic 1930s American thief.

Speaking at the U.K. premiere of "Public Enemies" in London's Leicester Square Monday night, Johnny said: "I had a sort of fascination, not so much that he was a criminal, that this guy took up arms against the establishment and he did it with a smile. There was a sort of twinkle in his eye which I find interesting. And the hat he wears, I did it for the hat.
