Johnny Depp, Miley Cyrus, and other stars show for the unveiling of Disney's upcoming movie slate

Disney just can't get enough of Johnny Depp. At yesterday's Walt Disney Studios Showcase, an all-day extravaganza of film previews and casting announcements, Disney revealed not one, not two, but three new projects for Depp. Dick Cook, the studio's chairman and the event's emcee, labeled the roles the "Depp trifecta." Might as well call it the "Depp monopoly."

First up is Tim Burton's live-action/CG adaptation of Alice in Wonderland, in which Depp has been tapped to play the part of the Mad Hatter. The movie is scheduled to be released in 2010.

Then, as the USC Trojans marching band played the finale of the William Tell Overture, Depp appeared on the Kodak Theatre stage dressed in his Jack Sparrow outfit and holding the Lone Ranger's mask. With just a few words of explanation, Cook confirmed it: Depp will star in a fourth Pirates of the Caribbean installment, as well as a Lone Ranger movie in which the actor will play the title character's sidekick, Tonto.

But the day wasn't all about Depp. Also stopping by to support their upcoming projects were Jim Carrey, Nicolas Cage, Robin Williams, John Travolta, Sandra Bullock, Dwayne Johnson, Tim Allen, Miley Cyrus, and the cast of High School Musical 3. Plus, there was a major casting announcement involving Oprah Winfrey. All of the juicy details are after the jump.

Let's split the Disney news into three categories: animated movies, live-action movies, and Jerry Bruckheimer movies (because, really, they're their own genre anyway).
