"Wishmaster was a great experience....I had a very short schedule and had to deliver the film into theatres in 6 months start to finish so it was very stressful but very fulfilling. Sam Raimi actually recommended me for the film and after a half a dozen meeting with the studio I got the job. I had to go in and pitch my take on the film and its design. We shot it in 33 days in LA which was tough as we had dozens of locations all around the city so we had a lot of company moves. We had hundreds of FX which was a bit of a challenge as the schedule was tight. I was very lucky to find Andrew Divoff and Tammy Lauren. Divoff is a very close friend who I enjoy working with on whatever we can find together. We now have this second hand when we work together." (Backwoods Horror interview with Robert Kurtzman in 2009)
According to a 2016 interview with PopHorror, it took 3.5 hours to get into costume with 1.5 hours to get out according to lead star Andrew Divoff. Ironically, he also said his favorite scenes for the film were the ones where he shared scenes with his monstrous brethren.

Joseph Pilato, who played the drunk crane worker in Wishmaster, was the main villain in Day of the Dead (as Captain Rhodes).
According to director Kurtzman on the Blu Ray special features, the studio originally wanted Dina Meyer to play the role of Alexandra.
Tammy Lauren appeared in the 1987 TV Movie "The Stepford Children" with I Dream of Jeannie star Barbara Eden.
