Two years ago, Johnny Depp told Newsweek that he'd only sign on for more Pirates of the Caribbean movies "if they had a good script." (Hey, it's not like he needs the work -- he's got the movie version of The Lone Ranger and Tim Burton's Alice in Wonderland already in the works!) Well, there must be some crazy stuff in store for Captain Jack Sparrow 'cause Johnny has signed on for a fourth Pirates flick, Variety reports.

Keira Knightley previously said that she's through playing Elizabeth Swann and wouldn't return for any more sequels. "I've been playing this girl since I was 17," Keira tells UK's Daily Mail. "I'm onto very different things." Does that mean Orlando Bloom will be a no show, too? Either way, it doesn't really matter to us -- we could watch Johnny as Captain Jack do the entire movie solo -- he could totally pull it off, too. Actually, that's not such a bad idea...
