A gay sexually graphic comedy has caused hardened film industry executives and film critics to walk out of the film's screening at the Cannes Film Festival in droves.

The British film, Nine Dead Gay Guys, which stars several British actors including veteran actor Steven Berkoff, Vas Blackwood, who appeared in Lock Stock and Two Smoking Barrels and Michael Praed, the former star of Dynasty, centers on two young men who left Belfast for London who became rent boys and their clientele of gay misfits, including a rich Orthodox Jew, a well-endowed black man, and an unhygienic Indian taxi driver.

Former Culture Club singer Boy George also guest stars as "The Queen" whose manhood is "the size and width of two Red Bull cans put together."

The controversial film stunned the audience with scenes that included a character dying as he is being violently sodomised and another flying through a car windscreen at the point of orgasm.

The film's backer and promoter, Hannah Rothman has, however, defended his film after the screening.

"It is just a light-hearted look at the scrapes these two boys get into. OK, these may include prostitution and killing people, but it is meant to be silly and not to be taken too seriously."
