I liked Chariots of Fire also. There is a documentary about Eric Liddle and the olympics that I found interesting. Liddell ran the 400 meters at a 100 meter pace.
Grizzlies Man, the documentary about the guy that lived with bears . What a jerk. This guy thought he was smart about bears and got himself and his girl friend eaten by one. He was supposed to be alone but had his girl friend with him. He had no clue what he was doing and ended up bear food. It was painful to watch stupidity and ignorance collid
