Johnny Depp as the Mad Hatter? Sounds brilliant — and according to one very well-informed source, it’s true. Tim Burton‘s upcoming take on the classic Lewis Carroll fairy tale, Alice in Wonderland 3-D is slated for release in 2010. The source reveals to that the film will be live action until Alice (played by Mia Wasikowska of HBO’s In Treatment) jumps down the rabbit hole and meets the loopy tea party host. The big question is whether Depp himself will don a Hatter outfit, or lend his voice to the computer-generated version. Disney and Depp’s camp won’t confirm whether the actor is set to play the nefarious charmer. No matter. We already know Depp looks great in a hat.
