Pulp star Jarvis Cocker was honoured to be at the London premiere of CHILDREN OF MEN, because a song of his used in the film is responsible for the new movie's R rating in the US. The British singer is grateful the film's director ALONSO CUARON still invited him to the bash, despite the movie's potential to make less money as a result of the more restrictive classification. Cocker says, "I came along tonight because I'm really grateful that Alonso included my song in the film. "The song has a lot of swear words in it, like c**t and f**k and the film's got an R in the US because of that. So it was a pretty brave decision."
