Christopher Walken! According to IMDB, he always tries to work a jig or dance into his movies. I have noticed he likes to dance...my fav being the Fatboy Slim video for "Weapon of Choice" which this portrait is a reference to. In my opinion one of the most versatile actors out there. Always plays the convincing creepy guy, unstable guy, funny guy, fatherly guy, etc. When it comes down to it, isn't that what we all want as artists? Versatility?
