Pola Weiss, the actress who played the groupie in this film, was interviewed by Colonel Kurtz on YouTube in 2021, after Evan Rachel Wood claimed that Weiss had been an underage fan and that Groupie was a snuff film depicting her murder. Weiss clarified that she is still alive, she was over 21 when she made the film, was hired as an actress for the film, and that the film was scripted.
The "groupie" in the film is an actress, not an actual fan. All scenes of BDSM are simulated.
The scene depicting consumption of urine was faked using slight of hand. One of the actors urinated into a cup, handed it off camera and switched it for a cup of apple juice. The footage was then edited to make it appear as if it was urine being consumed.
According to Pola Weiss, the inspiration for the film came from when Marilyn Manson was receiving a lot of death threats and decided to make a film as a form of therapy.
