The production that propelled her into the limelight was another Bone production, The World's Biggest Gang Bang. Quek took part in this gang bang on January 19, 1995, when she was 22 years old. She said part of her motivation to do the film was a desire to challenge gender roles.[citation needed] She appeared in advertisements on adult television to solicit 300 participants for the event. Initial reports differed as to whether she had sex with 251 men over the course of 10 hours, or with around 70 men multiple times to reach a total of 251: the largest number ever in a pornographic film. Acting on the understanding that male participants who had verified a recent negative test for HIV would wear a colour-coded tag, Quek had sex with some men without a condom. It later emerged that the testing had not been as strictly verified as the producers had led her to believe.[2][8] Even though the film became one of the highest-grossing pornographic films of all time, she was never paid the US$10,000 she was promised, and she apparently never received any money from the video.[1][8]
