ANAHEIM, Calif. (AP) -- Avast! Disney says a new "Pirates of the Caribbean" film is on yonder horizon.

Johnny Depp sailed onstage Thursday on a pirate ship in Anaheim, Calif., to help announce the forthcoming installment of Disney's blockbuster film franchise.

Depp will reprise his role as Capt. Jack Sparrow in "Pirates of the Caribbean: On Stranger Tides," slated for summer of 2011. It's the fourth in a series.

Chairman of Walt Disney Studios Richard Cook announced the news to about 5,000 fans on hand for D23, Disney's answer to Comic-Con. The first all-things-Disney convention runs through the weekend.
