Jerry Bruckheimer tells MTV that Geoffrey Rush has yet to sign on for a third Pirates of the Caribbean film- if the studio signs on for a third film, that is. “We’re hoping to start shooting [the second and third movies] in March, but we’re waiting for a very big check from Disney,” says Bruckheimer. Johnny Depp, Orlando Bloom, and Keira Knightley are all set to return for the sequel(s), while Keith Richards’ involvement in the film as the father of Jack Sparrow is still “premature”.
