On May 22, a classic movie adventurer returns. Indiana Jones and the Kingdom of the Crystal Skull is the fourth film in the series. Nearly 20 years have passed since Jones's last crusade. Joining him now is sidekick Mutt Williams, played by Shia Labeouf . The movie's plot is top secret. LaBeouf did not get a script until right before filming. But he didn't mind. "I would've paid them to be in it," LaBeouf told TFK.
