Disney has formally announced today that the Mad Hatter in Tim Burton's Alice in Wonderland [1] movie will be played by Johnny Depp [2] (of course!). The Hollywood Reporter has the scoop:

Depp and Burton. . . have formed one of the longest-running director-actor partnerships in modern Hollywood. And so when Burton committed to filming a new live-action/CG version of Alice, Depp was touted as the most likely candidate to play the Mad Hatter — after all, having worked with Burton on Charlie and the Chocolate Factory, he's practiced in wearing a top hat.

We also have a Tweedledee and Tweedledum — er, we have a Tweedle. Matt Lucas [3] will play both Tweedledee and Tweedledum.

The Johnny Depp news is no surprise, really, but it's exciting to know that it's a done deal! I wonder if the next announcement will be that Helena Bonham Carter is the Queen of Hearts?
