Dylan Jones: 'Thierry Guetta was simply meant to direct Banksy's film. Now he's selling everything with his name on it'

There has been a lot of chatter about the star of Banksy's film Exit Through the Giftshop, Thierry Guetta, aka "Mr Brainwash". The 44-year-old French artist was meant simply to direct Banksy's film about street artists, but soon became its principal subject – prompting many to suggest that: a) Brainwash was just a media prank, a convenient invention of Banksy's; or b) that he is actually Banksy himself. But if he is some kind of media construct, it appears to be working.

Exit Through the Gift Shop (15)

The secret location for the screening of this film – a cavernous brick vault beneath Waterloo Station – is an appropriate match to its director, the street artist and mystery provocateur Banksy.

Guerilla wallfare becomes a big draw

Banksy's latest "guerilla" graffiti has been graffitied over and the wall on which the offending vandals struck removed from public view in order to "restore" Banksy's original piece of art/vandalism. An ironic outcome, which will no doubt reignite the debate on whether Banksy has become part of the "establishment".

Philip Hensher: Computers have got a lot to learn about grammar

We're all getting, I fear, a computerised reading device for Christmas, allowing us to read the complete works of dozens of novelists through the magic of a seven-by-four screen. What happens if the logical conclusion is reached, and the computer takes to reading what we write, and judging it, too?

Support for Sutton's Banksy

A public vote on whether to keep a piece of Banksy graffiti in the London borough of Sutton has seen an initial wave of support for the renowned guerrilla artist.
