Shia Labeouf has confirmed movie bosses are planning to bring Indiana Jones back for a fifth time - a new film in the archaeologist adventurer series is in the works.

LaBeouf joined Harrison Ford in the movie franchise's fourth instalment, Indiana Jones and the Kingdom of the Crystal Skull, last year and played the history hero's son and sidekick Mutt.

After the global success of the film, which came nearly 20 years after 1989's Indiana Jones and the Last Crusade, rumours began swirling that director Steven Spielberg planned to continue the franchise without Ford - passing the lead to the young Transformers star.

And now the actor has confirmed the legendary director is working on another Indiana Jones picture - but refuses to reveal any of the details.

He says, "Steve just said that he cracked the story on it, and I think they're gearing that up."

Ford and LaBeouf have both dismissed reports that the younger star will be leading the Indiana Jones franchise in the future, even though LaBeouf recently told Playboy magazine that his movie father handed him his iconic hat as a parting gift on the set of the last film.
