Jack Nicholson celebrates his 77th birthday today, and we honor Jack with a look back at some of his greatest performances.

With more than 60 movies to his credit, has anyone seen every Jack Nicholson movie? Certainly not me, but what I have seen, I have liked a lot.

Nicholson has represented a broad and versatile spectrum of characters from the horrifying(The Shining, Batman) to the dramatic (One Flew Over The Cuckoo's Nest, A Few Good Men) to comedy (Anger Management, Something's Gotta Give)

While Nicholson has gained the reputation as one of Hollywood's bad boys, on the screen he has been one of the greatest actors of our time.

Here's a couple of classic moments, from The Shining, and A Few Good Men, plus an in-depth look at Jack's top ten movie performances.
