If someone has ever asked you for more cowbell or you've danced along to Fatboy Slim's, "Weapon of choice," then you've most likely heard of Christopher Walken. Chances are you've even tried out your own Walken impersonation. "All About Walken" is a play running in its third year which serves as both homage and send-up to the actor who has appeared in over ninety movies spanning over forty years.
