The work of mindless vandals or creative geniuses? To some it’s art, to others it’s a sign we’ve lost control of our cities. Since Roman times graffiti has been a form of anti-establishment rebellion. But today it has transcended social nuisance to gain artistic credibility, unprecedented prices at auction and even Presidential and Prime Ministerial approval. Director Jane Preston explores the creative conflict between graffiti legend King Robbo and the media darling stencil artist Banksy; a spat that has been described as the biggest art rivalry since Picasso and Matisse. The film goes behind enemy lines as the war escalates.
