The announcements just keep coming today from the Walt Disney Showcase in Hollywood. It was announced today that Johnny Depp has signed on to play the Mad Hatter in Tim Burton's upcoming adaptation of Alice in Wonderland, a role he was previously rumored to be attached to.

Mia Wasikowska and Matt Lucas have already signed on for the project, which Tim Burton will direct from Linda Woolverton's script. It is said that the film will combine live-action and motion-capture footage, much like Beowulf did.
