Matt Damon Makes Surprise Appearance in Movie

Eagle-eyed movie fans will spot Matt Damon in best pal Ben Affleck's new thriller "The Sum of All Fears" - as a waiter.

According to set reports, Damon donned a waiter's outfit to play a joke on his friend for one scene in the film - and the scene wasn't cut from the finished film.

Apparently, Affleck was so engrossed in his role as hero Jack Ryan that he didn't notice he was being served by his pal.
