But he's sure that if producers and director Catherine Hardwicke had known how big a film the vampire love story would become, they'd have reached out to the world's top bands straightaway.

He says, "It was nice to be involved in the first soundtrack. I just saw Twilight on TV for the first time a few days ago and when my songs came on I thought, 'That's so bizarre that I actually had those songs in the movie'.

"I'm kind of amazed that Catherine did it. But it really shows that nobody thought it was going to be so massive. I didn't think anybody was going to buy the soundtrack."

And Pattinson admits that catching his tunes in Twilight on TV has given him the hunger to record more songs for the film franchise.

He adds, "Maybe I will do more songs (for the soundtrack)."
