While having Tim Burton working on Alice in Wonderland is an obvious plus, having a solid musical score is still required. It's a dark fantasy, so we're going to need something dark and brassy. Who to turn to for such a sound?
While there are quite a few big name composers I can think of, it still comes as no surprise that Tim Burton is looking to Danny Elfman to at least create a part of the film's score.
Straight from the horse's mouth, Elfman has confirmed his involvement on Alice in Wonderland during a panel at the El Capitan theater in Hollywood.
