The New York Times asks Al Jean, an executive producer from The Simpsons about the making of the Banksy-directed intro:
Q. How did you find Banksy to do this, and now that it’s done, how much trouble are you in?
A. Well, I haven’t been fired yet, so that’s a good sign. I saw the film Banksy directed, “Exit Through the Gift Shop,” and I thought, oh, we should see if he would do a main title for the show, a couch gag. So I asked Bonnie Pietila, our casting director, if she could locate him, because she had previously located people like Thomas Pynchon. And she did it through the producers of that film. We didn’t have any agenda. We said, “We’d like to see if you would do a couch gag.” So he sent back boards for pretty much what you saw.
Q. Were you concerned that what he sent you could get the show into hot water?
A. I’d be lying if I said I didn’t think about it for a little bit. Certainly, Fox has been very gracious about us biting the hand that feeds us, but I showed it to Matt Groening, and he said, no, we should go for it and try to do it pretty much as close as we can to his original intention. So we did. Like we always do, every show is submitted to broadcast standards, and they had a couple of [changes] which I agreed with, for taste. But 95 percent of it is just the way he wanted.
Q. One of the things Banksy is known for is disguising his identity. How can you be sure that you were dealing with the real him?
A. The original boards that we got from him were in his style and were certainly by an extremely proficient artist. We were dealing with the person that represented him making the movie. I haven’t met him, I don’t even know what he looks like, except what the Internet suggests. And he’s taken credit for it now so I’m pretty sure it’s him. We went through the people that made the movie so I assume they would know how to get to the real him.
