Although the movie is simply a document of an interview with Stephen Prince, the film becomes so much more. Scorsese truly gives the viewer an in depth view into the man's life; mostly due to Prince's wonderful role as a story teller. Some of the tales he tells are fascinating, some silly, some so outlandish you have to doubt their sincerity. Extremely entertaining, and a prerequisite for any Tarantino fan -- see the film and you'll see what I mean.
