The Simpsons. October 2010.

As reported by Simpsons Wiki (https://simpsonswiki.com/wiki/Banksy_couch_gag):

Banksy is credited with creating the opening titles and couch gag for this episode, in what amounted to the first time that an artist has been invited to storyboard the show. Executive producer Al Jean first took note of Banksy after seeing his 2010 film Exit Through the Gift Shop. According to Jean, “The concept in my mind was, ‘What if this graffiti artist came in and tagged our main titles?'” 

Simpsons casting director Bonnie Pietila was able to contact the artist through the film’s producers, and asked if he would be interested in writing a main title for the show. Jean said Banksy “sent back boards for pretty much what you saw.” Series creator Matt Groening gave the idea his blessing, and helped try to make the sequence as close to Banksy’s original storyboards as possible. Fox’s standards and practices department demanded a handful of changes, but, according to Jean, “95 percent of it is just the way he wanted.”

Banksy told The Guardian that his opening sequence was influenced by The Simpsons long-running use of animation studios in Seoul, South Korea. The newspaper also reported that the creation of the sequence “is said to have been one of the most closely guarded secrets in US television – comparable to the concealment of Banksy’s own identity.”

Response

BBC News reported that “According to [Banksy], his storyboard led to delays, disputes over broadcast standards and a threatened walk out by the animation department.” However, Al Jean disputed this, saying ” [The animation department] didn’t walk out. Obviously they didn’t. We’ve depicted the conditions in a fanciful light before.” Commenting on hiring Banksy to create the titles, Jean joked, “This is what you get when you outsource.” Although conceding to the fact that The Simpsons is largely animated in South Korea, Jean went on to state that the scenes shown in titles are “very fanciful, far-fetched. None of the things he depicts are true. That statement should be self-evident, but I will emphatically state it.”

Colby Hall of Mediaite called the sequence “a jaw-dropping critique of global corporate licensing, worker exploitation and over-the-top dreariness of how western media companies (in this case, 20th Century Fox) takes advantage of outsourced labor in developing countries.” Melissa Bell of The Washington Post felt Banksy’s titles had helped revive The Simpsons’ “edge”, but after “the jarring opening, the show went back to its regular routine of guest cameos, self-referential jokes and tangential story lines.” Marlow Riley of MTV wrote “as satire, [the opening is] a bit over-the-top. What is shocking is that Fox ran Banksy’s ballsy critique of outsourcing, The Simpsons, and the standards and human rights conditions that people in first world nations accept. It’s uncomfortable and dark, and not what’s expected from the modern Simpsons, which mainly consists of ‘Homer hurts himself’ jokes.”

Banksy published a clip from the Simpsons on his Youtube-channel Banksyfilm:

Street Art UK. 2010

After Banksy’s tour of the US following the premiere and promotion of Exit Through the Gift Shop, he was back in the UK for the summer and fall of 2010. He also visited Glastonbury, where he stencilled the crazy hippies and filmed a prank with Prince Charles.

Exit Through the Gift Shop at Sundance film festival. January 2010

The film premiered at the 2010 Sundance Film Festival on 24 January 2010 and was later nominated to the Oscars and the BAFTAs for Best Documentary Feature. The synopsis was described the following way on the official website:

“This is the inside story of Street Art – a brutal and revealing account of what happens when fame, money and vandalism collide. Exit Through the Gift Shop follows an eccentric shop-keeper turned amateur film-maker as he attempts to capture many of the world’s most infamous vandals on camera, only to have a British stencil artist named Banksy turn the camcorder back on its owner with wildly unexpected results.  One of the most provocative films about art ever made, Exit Through the Gift Shop is a fascinating study  of low-level criminality, comradeship and incompetence.  By turns shocking, hilarious and absurd, this is an  enthralling modern-day fairytale… with bolt cutters.”
