The film director who was charged for screening controversial gay porn film LA Zombie says he will not defy the classification board again.

Richard Wolstencroft caused a stir last August when he played the film at his Melbourne Underground Flim Festival despite the board's refusal to approve it for showing.

He has now been ordered by a court to give $750 to Melbourne's Royal Children's Hospital.

Wolstencroft claims he has learned his lesson after being dragged through the legal system.

"Obviously I really do like to push the envelope and play different material, but look, I submit a list of films and if they reject one of two, it's not going to play," he said.

Under classification laws he faced a maximum penalty of a $28,000 fine or two years in jail for playing the film.

Having escaped a conviction, Wolstencroft says he is glad he escaped with just a fine.

"I'm not going to do that again, you know what I mean?" he said.

"It's been a bit of a nightmare to be honest; getting charged with anything. If I knew I would be charged I wouldn't have gone ahead and done it."
