Banksy has also been long criticised for copying the work of Blek le Rat, who created the life-sized stencil technique in early 1980s Paris and used it to express a similar combination of political commentary and humorous imagery. Blek has praised Banksy for his contribution to urban art, but said in an interview for the documentary Graffiti Wars that some of Banksy's more derivative work makes him "angry", saying that "It's difficult to find a technique and style in art so when you have a style and you see someone else is taking it and reproducing it, you don't like that."
Local residents of Weston-super-Mare were told that a Hollywood company called Atlas Entertainment was using the location to film a crime thriller called Grey Fox. Signs proclaiming "Grey Fox Productions" were posted around entrances to the site. Pictures of its construction began surfacing online in early August 2015, and included a "fairy castle and massive sculptures". Holly Cushing, whose name appeared in the credits of a documentary about Banksy and who is often reported to be his manager, was sighted at the construction site before the opening, which contributed to the decline of its status as "secret".
In late January 2011, Exit Through the Gift Shop was nominated for a 2010 Oscar for Best Documentary Feature. Banksy released a statement about the nomination, stating, "This is a big surprise... I don't agree with the concept of award ceremonies, but I'm prepared to make an exception for the ones I'm nominated for. The last time there was a naked man covered in gold paint in my house, it was me." Leading up to the Oscars, Banksy blanketed Los Angeles with street art. Many people speculated if Banksy would show up at the Oscars in disguise and make a surprise appearance if he won the Oscar. Exit Through the Gift Shop did not win the award, which went to Inside Job. In early March 2011, Banksy responded to the Oscars with an artwork in Weston-super-Mare, UK, of a little girl holding the Oscar and pouting. Many people think that it is in reference to 15-month-old Lara, who dropped and damaged her father's (The King's Speech co-producer Simon Egan) Oscar statue. Exit Through the Gift Shop was broadcast on British public television station Channel 4 on 13 August 2011.
Among the structures photographed prior to the opening were a large pinwheel by Banksy, Horse Scaffolding Sculpture by Ben Long, and a twisted truck sculpture, Big Rig Jig by artist Mike Ross which was previously shown at Burning Man in 2007. Works by 58 artists, including Jenny Holzer, Damien Hirst, Jeff Gillette, Jimmy Cauty and Bill Barminski were featured in the park. Banksy said he contacted the "best artists I could imagine" to exhibit, with two artists turning him down.
