A daylong preview of upcoming Disney movies and projects, held Wednesday at the Kodak Theatre at Hollywood & Highland, ended with a surprise appearance by the actor, outfitted as Jack Sparrow, walking onstage to the tune of "The William Tell Overture," the Lone Ranger theme. The Depp castings were just a couple of the developments that Disney execs, led by chairman Dick Cook, offered up to a packed house of exhibitors and media types. In lieu of doing major presentations at industry confabs like ShoWest, Disney traditionally throws elaborate show-and-tells in Los Angeles every few years to promote its wares.Those wares include competition for Depp as the default Mouse Heir: Another report places Nicolas Cage in an updated Sorcrer's Apprentice, set in present-day New York and featuring Cage as the Sorcerer. We have 10 bucks on Miley Cyrus as the title character. Seriously, Mickey, nut up and come back anytime — all is forgiven.
