ET headed to Hollywood for the premiere of the true crime drama 'Public Enemies,' with Christian Bale and Johnny Depp who proved that although they aren't public enemies in real life they are definitely two of Hollywood's most wanted men!

In the film Depp plays notorious 1960's bank robber John Dillinger, and Bale plays Melvin Purvis an FBI agent working to put Dillinger behind bars.

Depp explains to ET why he feels the public was so drawn to the charismatic outlaw.

"I don't know that John Dillinger's a bad guy," he says. "Maybe the title of the film is 'Public Enemies', but I wouldn't say he's an enemy of the public."

The talented actor also opens up about swirling rumors that he could play the Riddler, and star alongside Bale in the next Batman film.

"I don't know you know I've been asked about that here and there ," he says. "I'd love to do another film with Christian in any capacity, whether it's a batman thing or whatever it is. I certainly love the series."

ET also caught up with Marion Cotillard and director Michael Mann. Click the video to watch.
