We love it when big stars get star struck. This is a great story that John C Reilly told to Conan about getting star struck while filming a movie with Jack Nicholson. During the shooting of the movie, Jack Nicholson invites John C Reilly to go see the band U2. It isn't the concert, per se, that is the interesting part. It is WHEN and WHERE Jack Nicholson asks if John wants to go to the concert. And it is also the dancing the Jack Nicholson did at the U2 show. All we know is that we want to go see a concert with Jack Nicholson!
