Exit Through the Gift Shop (2010)
Director: Banksy
Runtime: 87 min

Thierry Guetta (born in Paris, lives in L.A) was for many years obsessed with video cameras and documenting every moment in his life, until he discovered street art which became his new obsession. Or maybe the whole thing was made up and planned by Banksy and Shepard Fairey, who wanted to express harsh criticism of the commercialization of street art? Regardless of whether this film is a genuine documentary or not, it presents a very interesting way of dealing with the issues of authenticity and commercialization, both of art and life.
