The movie follows the journey of Thierry Guetta, a French shop owner who becomes obsessed with filming street artists. He captures footage of some of the most prominent artists, including Shepard Fairey and Banksy, but fails to make a cohesive film. Banksy takes pity on Guetta and decides to switch roles, becoming the director of the movie. However, as the project progresses, it becomes unclear whether Guetta is a genuine artist or just seeking to capitalize on the street art movement's popularity.
The film explores themes of art, authenticity, and the commercialization of street art. It features interviews with many prominent figures in the art world, including Fairey, Banksy, and street artists Invader and Space Invader.
The movie received critical acclaim and was nominated for the Best Documentary Feature at the 83rd Academy Awards. It remains a popular and controversial look at the street art movement and the culture surrounding it.
