Harrison Ford has taken on a grueling fitness regime to get into shape for the return of Indiana Jones later this year. After an 18-year break from the action adventure franchise, Ford, 64, is determined to get his body back on top form for his reprisal of the famous role.

His girlfriend, actress Calista Flockhart, says, "He's on a strict high-protein diet. He's eating lots of fish and vegetables. It's hard but he's already looking great for it. He wants to make sure Indy is as tough as he always was."

The fourth film is scheduled for release in 2008 and follows Indiana Jones And The Last Crusade, which came out in 1989.
