Simpsons creator Matt Groening has revealed that Green Day do appear in the upcoming Simpsons movie. According to previously reported reports, a spilt second clip of the band has appeared in a trailer for the film, which is presumably what prompted MTV news to corner Groening at the show's 400th episode celebrations in Los Angeles. He was far more forthcoming than Green Day's label Reprise, or the film's backers 20th Century Fox, saying: "Green Day is in the movie - I will publicly acknowledge that Green Day are in the movie. They're really good sports and I think we both honour them and 'Simpson'-ise them. You can take that however you want. They're really nice guys".
The show's Hank Azaria also gave some info away, saying that one of the many characters he voices, Moe, abuses the band as they perform. Co-star Yeardley 'Lisa' Smith said she didn't know that Green Day were in it; which may be explained by the fact that there are, according to Nancy 'Bart' Cartwright, nearly 400 guest appearances in the film. It's out 27 Jul. I can't help but feel quite excited about it, but also slightly worried.
