This movie is all about the life of comedian Robert Klein. In this film, there are many interviews with Jerry Seinfeld, John Stewart and Richard Lewis while there are various tires along the way.
The film, directed by Marshall Fine, does an excellent job of reintroducing Klein to a generation younger than the comedian's: Klein is now a hale and hearty 75 years old.
There's something special in watching a documentary about someone you aren't familiar with, and then really enjoying it. It's like the filmmaker has given you a gift.
