"Public Enemies" to film in Madison in early May

"Public Enemies" is scheduled to film in Madison during the first part of May. While Johnny Depp stars in this Michael Mann film, he's not reported to be in every scene filmed in Madison. My best guess would also have Christian Bale who plays FBI "G-Man" Melvin Purvis and Billy Crudup who's portraying FBI crime czar J. Edgar Hoover in some of these Madison scenes.

Here's more about the filming in Madison;
