Former Pulp star Jarvis Cocker has vowed to write more songs for film following the success of his music in Harry Potter AND THE GOBLET OF FIRE and CHILDREN OF MEN. The vocalist, who also had a small part in the Harry Potter movie as lead singer of wizard pop act THE WEIRD SISTERS, reveals he would like to branch out into comedy. He says, "I want to do a comedy next, like a Richard Curtis type love fest. I secretly like those type of movies."
