Indiana Jones 4: According to Female First, Harrison Ford has been given strict instruction on exercise ahead of his fourth outing as Indiana Jones - don't do any.

The 62-year-old megastar has been told to get his Fedora and whip ready for a January 2005 shoot for Indy 4 but not to go mad on getting buff for the role.

"It's been 15 years since the last Indy movie and obviously Harrison has got a lot older but that's not a problem for this movie," says an insider on the Steven Spielberg-directed future blockbuster.

"Steven doesn't want a middle-aged guy trying to look young - he wants to bring a new type of hero to the screen.
