HBO's innovative stab at meta-fictional comedy, Curb Your Enthusiasm features former SNL and Seinfeld writer Larry David playing himself, cast against a variety of real and fictional characters. Curb Your Enthusiasm is based on the HBO special Larry David: Curb Your Enthusiasm. Curb Your Enthusiasm gives self-indulgence a wide berth, becoming less a comedy of the life of a Hollywood writer, and more of an intelligent and thought provoking expose on the human condition.
