Movie star HARRISON FORD is in talks to star in JAMES CAMERON's new epic - in 3D.

Hollywood has so far kept quiet about the project, which will be a science-fiction extravaganza - according to gossip site THE
SCOOP.

But Ford is reportedly slimming down for the film, because he fears 3D cameras will make him look fat.

According to sources, a technical expert warned him, 'If the normal camera adds 10 pounds, think how a 3-D camera can blob you up.'
