Jack Black has revealed he's unlikely to ever lose a lot of weight simply to get an acting role.

The rotund Tenacious D star felt he "sold out" playing the romantic lead in looks and weight-obsessed film Shallow Hal and doesn't want to go for roles in the future where his weight might me an issue.

He said recently: "I don’t get hung up on weight. If a director said I'd get a role but I'd have to lose five pounds, I could do that by tomorrow -- losing the first few pounds is easy."

"But if someone asked me to lose, say, 30 pounds (2 stone) for a film, it'd have to be an awfully cool part. And nothing's coming to mind right now."
