The scheisse is about to hit the fan.

Following 2006's "Borat," Sacha Baron Cohen is about to unleash his latest theatrical project, Friday's "Bruno." And while devotees of the British comedian's ambush comedy will be in heaven, those who got duped into appearing in the film will probably want to move permanently into a potato cellar.

The Bruno character, a flamboyant Austrian TV host who's equally in love with his tiny Filipino boyfriend and shimmering thongs, gets fired after disrupting a fashion show in Milan. He heads to America and travels the country, interviewing (and occasionally making obscene, on-camera passes at) ministers, psychics and former presidential candidate Ron Paul. Like "Borat," it's full-on cringe-ertainment.

The Post talked to six people involved with the film — including four victims duped into appearing — to get their stories and figure out how, even after the massive success of "Borat," there are still people unfamiliar with Cohen's shtick. One didn't even know he was in the film until The Post phoned.

Victim: Dr. Paul Cameron, chairman of the Family Research Institute, Colorado

Scene: Bruno comes to him for advice on going straight.

"I did a German thing a year ago. Is that this? I wondered what had happened to that. I'm in this bloody film? Well, I'll be jiggered. I guess you never can believe when people are in distress.

"I had to go to Kansas City. I was told that this chap was a homosexual in Germany, had a popular TV program in Germany, was perhaps suicidal and wanted to [become straight]. And I was supposed to see if I could help him in some way.

His producer was telling people what to do. He'd say, 'Here's the setting. This will be your office. He'll come in, give him the kinds of advice that will be useful for him.' It took about two and a half, three hours. To put it mildly, a few of his questions seemed strange. When he tried to sit by me and he wanted to give me a b - - w job, that kind of stuff pushed it.

"If it's a gag, it was pretty well staged. I'll be another laughing stock. Oh, well."
