From Bansky, the world's greatest and most elusive graffiti artist, comes the 'the world's first street art disaster movie.' For over a decade, eccentric superfan Thierry Guetta has been recording street artists at work. His footage provides a unique glimpse into a shadowy subculture but his attempts to locate and befriend Banksy end spectacularly with the artist turning the camera back on its owner. Guetta is a keen cameraman but a rubbish filmmaker and his edit of the footage is a disaster, so Banksy takes over, but at the same time creates a monster: Guetta becomes an artist and a celebrity. But is this tale of low-level criminality, companionship and incompetence a true story or another Banksy creation? Genuine or not, it's still a provocative, questioning and very funny look at creativity and fame.
