Andrew Divoff was set to reprise his role as The Djinn in Wishmaster 3 and in 1999, he had even written a script for a third entry entitled Wishmaster: The Third Millennium, that would have revolved around the panic surrounding Y2K at the time. Divoff's script would have opened with an American warship getting struck by a missile in Asia, while a meeting at the UN is interrupted by creatures coming to life and tearing apart the crowd. According to an interview with Divoff, a lot of thought was put into his script. But when he presented his script to the producers, they turned it down, feeling it was too ambitious and expensive to make so they went with Alex Wright's script instead. Divoff read it, hated it and left.
Filmed back-to-back with O Mestre dos Desejos 4 (2002). There essentially was a weekend between filming the two movies in 2000.
Both the third and fourth films were shot on a tight 16 day scheduled shoot according to the director Chris Angel.
Was filmed in Winnipeg, Manitoba, Canada.
A lot of scenes were shot with two cameras.
