Banksy is the world's most infamous street artist, whose political art, criminal stunts and daring invasions have outraged the establishment for over two decades. Featuring rare interviews with Banksy, this is the story of how an outlaw artist led a revolutionary new movement and built a multi-million dollar empire, while his identity remained shrouded in mystery.

A look at the feud between graffiti artists King Robbo and Banksy.

From the streets of Bristol to the caverns of London and beyond, BanksyDoc finds the truths and explores the impact that the world’s most famous graffiti artist has had on the art world, on the expression of protest and satire, and on the perception of what you can do with a spray can and a stencil. Furthermore, this documentary explores the highly active art collector's world and how the celebrity factor shockingly influences value.

Banksy’s work now reportedly changes hands for millions. But he puts up his street art for free. Have you ever wondered what would happen if you got your hands on one of these? Does it mean you’ve found a winning lottery ticket or just scraped some worthless crap off a wall? Going up against the Art Establishment, Critics, Auction Houses, Gallery Owners and Authentication Boards in a quest for the elusive meal ticket, two filmmakers unwittingly gatecrash the murky and protective world of Banksy. “HOW TO SELL A BANKSY” raises questions of ownership, authentication and the true value of art itself. Through all the chaos and incompetence comes a modern-day, true-story, crime-theft, comedy-caper.

The exit door of the Bataclan theatre, the site of Bansky's mural, The Sad Girl, is stolen mysteriously. After it abruptly appears on of a hillside cottage in Abruzzo, French and Italian investigators unite to get to the bottom of the theft.
