Capturing the Friedmans
Grizzly Man
Capturing the Friedmans is good.
Here is one that the entire board will love.
This is the guy that wrote Boondock Saints and was a bartender (I think) and was given an insane deal of writing, directing, casting, soundtrack, full control and over a million dollars. You watch this guy come from nothing, get the big head, treat people like ****, lose everything, and fail.
The funny thing is, he sold his rights to this company just to get the movie released. When it became a cult classic and sold a ton of DVDs, he got none of the money from it.
