Disney is full of surprises today. According to Variety, Depp has agreed to reprise his role as Captain Jack Sparrow in a fourth "Pirates of the Caribbean" pic and play Tonto in a bigscreen adaptation of "The Lone Ranger," both produced by Jerry Bruckheimer. He will also star as the Mad Hatter in Tim Burton’s version of "Alice in Wonderland."

Disney is milking their cash cow, and as the saying goes even if there really isn't any, "Anything with Johny Depp is good".

Depp’s casting deals closed a full day Wednesday at the Kodak Theater, where Walt Disney Studios chairman Dick Cook touted the Mouse’s upcoming slate of pics during a showcase event for exhibitors, media and other industry insiders.
Obviously, the spotlight's not just on Johny Depp but also Jerry Bruckheimer who's also be doing, National Treasure 3 with Nicolas Cage.

No mention of release dates for Pirates 4, or, at least I didn't catch that at all.
