10. Exit Through the Gift Shop
This no-frills documentary is a must because it lets us see Banksy, the elusive British graffiti artist, launch his illegal bursts of creativity on walls and buildings. Banksy lets French videographer Thierry Guetta shoot his work. Then, when Guetta starts making his own art, Banksy switches roles and directs a movie about Guetta. The line between making guerrilla art and selling out has never blurred more provocatively. The visuals are amazing.
Key Scene: You pick it. The film shows work before it is painted over or removed. The DVD lets you hit the pause button, study it and decide whether it's art or nonsense.
