Sacha Baron Cohen’s latest film about his alter-ego Bruno, an outlandish Austrian gay fashion reporter, has already caused controversy despite not being released until July.

A Republican candidate for last year’s US presidential election, Ron Paul, revealed how he was lured into a hotel room by Cohen after being convinced that he was to be interviewed on Austrian economics.

Cohen then started to strip in front of him.

Mr Paul told America’s ABC Radio: “We were in a studio situation, I wasn’t invited into a hotel room. There were lots of lights and blaze and commotion and they said we better get in this back room which had been fixed up as a bedroom.

“By the time he [Cohen] started pulling his pants down, I was like what on earth is going on here and I ran out of the room. This interview had ended.”

He continued: “I don’t like the way he lies his way into interviews. That to me is fraud.

“He has raunchy material people buy into … it’s sort of sad that it’s a reflection of our culture. It’s a real shame people are gonna reward him with millions and millions of dollars for being so crass.”

Mr Paul is a notable opponent of gay marriage, having said in 2004: “Many Americans understandably fear that if gay marriage is legalised in one state, all other states will be forced to accept such marriages.”

The new film follows the huge success of Ali G in Da House and Borat: Cultural Learnings Of America For Make Benefit Glorious Nation Of Kazakhstan and contains extremely lewd behaviour, forcing some scenes to be cut from the final version.

Cohen also ridicules Madonna’s adoption of a Malawi child, by collecting an African baby from a box on an airport carousel, later claiming that he called him “a traditional African name – OJ.”

The film also sees Cohen crashing the Milan Fashion Week by wearing clothes made entirely from Velcro.

In November, Cohen attempted to gatecrash a Proposition 8 rally in California as Bruno.

He arrived at the rally in Los Angeles sporting a blond wig and marched, but was uncovered by other protestors and escorted away.

Bruno is released in UK cinemas on July 10th.
