Jack Black has vowed never to star in a biopic of late comedian John Belushi - fearing it would tarnish the reputation of his comedy idol.

The School Of Rock star is convinced it's a mistake to hire present-day funnymen to play legendary comedians because their life stories can be deeply tragic. And the actor insists that if he was offered the chance to play Belushi, he would turn it down.

He says, "I think it falls into that trap of when a comedian is playing a comedian it's just less funny. His (Belushi's) life is not as funny as his work, and watching me do an imitation of him doing his Saturday Night Live bits won't be as funny as watching him do his SNL bits. I think it falls into that category of when Jim Carey did Man on the Moon (the Andy Kaufman movie). Just because the guy is an amazing and compelling artist doesn't mean that telling his story is going to be interesting to watch."

John Belushi died of an overdose in 1983 at the age of 33 after a long battle with alcohol and drugs.
