Jack Nicholson, the movie legend and multi-Oscar winner, was supposedly quite a riot on Martin Scorcese's movie set for "The Departed".

According to radarmagazine.com, the actor used to do his usual clowning around but also went as far as to tinker with the script.

Nicholson, who is an avid fan of the basketball team the Los Angeles Lakers, even had people banned on the set from wearing the rival's Boston Celtics shirts while they were filming in Boston.

When questioned about Nicholson's antics, his agent only said, "I have no idea. I wasn't there."
