Watch Joseph Gordon-Levitt Teach Conan O'Brien How to Headbang
It has been a big week for Joseph Gordon-Levitt. Not only was he officially added to the cast of The Dark Knight Rises -- though maybe not as who you thought he was going to play -- but JoGo also got to trash the set of Conan, under the guise of headbanging instruction. The things he'll do to plug Hesher! Click ahead to watch the fun mayhem.

It's nice to see that late night talk shows can still exude that old "ring-a-ding" essence once in a while.
I have loved many of the choices JGL has made movie-wise, but he came off as a bit of a tool on Conan. Especially after following Reese Witherspoon, who seems like loads of fun. At least the headbanging showed he had a pulse.
