A Melbourne filmmaker whose home was raided over a public screening of a zombie porn film has slammed the police action as "perverse".

Richard Wolstencroft's home was raided yesterday, nearly two months after he held a public screening of the banned movie LA Zombie in August.

The founder and director of the Melbourne Underground Film Festival (MUFF) says the raid was "absurd, ridiculous and perverse", and he wants to know why it took the police so long to act.

"Why was it (the raid) delayed six weeks? Why was I not charged two days later?" he told ABC News Online.

"Why did they (police) not come to the screening and let me know they had a problem and then we could have avoided this situation altogether.

"I just think the timing of this is interesting. Two weeks before the Victorian election ... I'd like to look at the politics behind it - why this has happened at this moment."

The Australian Classification Board banned the film just before it was due to be screened at the Melbourne International Film Festival (MIFF) in July.

The film, directed by Canadian Bruce LaBruce, is described in the festival program as "gay zombie porn".

Police say the home was raided "in relation to exhibiting and possessing an unclassified film" and that Wolstencroft is expected to face court at a later date.

Wolstencroft says he has not yet been charged, but is worried he will get a criminal conviction and not be able to travel to the United States.

"As a working filmmaker I travel to America. I'm talking to Hollywood producers about doing my next film - that's a major concern," he said.

Wolstencroft is also suspicious about why police picked his house to raid.

"This is the first time a film festival director has had his house raided. Why didn't they raid Richard Moore from the Melbourne International Film Festival? I'm sure he's got a copy," he said.

"He was going to play it, he was all over the media saying he was going to play it. I heard they were handing out copies to the media at the Melbourne International Film Festival.

"The copy we did have briefly was one of those copies.

"I think they're targeting MUFF because it's a little independent film festival. They're picking on the little guy."

Freedom of speech

Wolstencroft says he expected police to show up at the public screening but, when they did not show he thought he was in the clear.

"We were waiting for them (police) to turn up; we had a stand-by film we were going to play as a replacement film," he said.

"We tried to play a lesbian film a few years back and the police did turn up at the screening. I thought something similar would happen here if they had a problem with the screening."

Wolstencroft, who has long been vocal about freedom of speech, says during yesterday's raid three police officers threatened to take all of his DVDs, including films he is working on.

"I have a personal collection of DVDs. I have the entire MUFF archive here - there must be 10,000 DVDs in my house," he said.

"They threatened to take all this and obviously it would be held up for six months. It was just ridiculous."

He says the banning of LA Zombie is a prime example of Australia's censors going too far.

"There is no way this film should be banned. It's a major work of art," he said.

"I've seen video installations at the Australian Centre for Contemporary Art, the National Gallery in Canberra that have been more offensive, more outrageous," he said.

"It's playing at major film festivals - the Locarno Film Festival and the Toronto Film Festival.

"If this was playing in a gallery, there is no way the police would come anywhere near it."
