Dimension Films placed the cast and crew under a gag order, hindering Rick Bota's opportunity to promote the film when Fangoria magazine attempted to do a cover story on the film. Star Ashley Laurence broke the gag order to speak about the film, claiming that she had only been paid enough money to make a payment toward a new refrigerator.
(at around 35 mins) Director Rick Bota was initially ambivalent about the idea of Pinhead appearing through an acupuncture chart, thinking it was too silly, but Doug Bradley was so amused by the idea that it was kept in the script.
Like Hellraiser: Inferno (2000) before it, "Hellseeker" was originally a non-Hellraiser related horror script owned by Dimension (though the director of Hellraiser: Inferno (2000) Scott Derrickson maintains the film was always written and intended as a Hellraiser sequel.) To save money on writing a completely original Hellraiser story, the script was quickly edited to insert the Cenobites and references to Kirsty's past with them. A scene written specifically to try and bring the largely unrelated plot in line with the canon of the first two Hellraiser films was subsequently cut, but is available on the DVD as a special feature.
(at around 51 mins) The uncredited coworker who interrupts Trevor and Bret at the water cooler was referred to by director Rick Bota as a "$10,000 extra." Labor laws of British Columbia forbade directors from directly instructing non-speaking extras - all orders had to be conveyed through the assistant director - and after Bota told the man to play the scene differently, the man was due a few thousand dollars in compensation.
