Johnny Depp will play the legendary gangster while Bale will play Melvin Purvis, the FBI agent tracking him down.
So far, this is a hell of a cast. Also, it is directed by Michael Mann, and let's face it: Nobody makes a crime drama like Mann. The man (or Mann) is a legend in the crime genre, be it the original (and best) Hannibal Lecter film Manhunter (in which the iconic villain is spelled Lecktor), television's Miami Vice or the 1995 masterpiece Heat - Mann knows how to show both sides of the law.
Depp is Hollywood's golden boy at the minute and Bale seems to be attaching himself to a wide variety of films, possibly to avoid type-casting as Batman. With these actors attached to the film, it should be a powerful piece of intelligent cinema with strong performances. It really is a film to look forward to.
The film goes in front of the camera in March and there is no release date set.
