Originally meant to be "Conan the Conqueror", the script was rewritten as "Kull" for Kevin Sorbo when Arnold Schwarzenegger refused to reprise his Conan character.
Tia Carrere, Roy Brocksmith, Sven-Ole Thorsen, and Pat Roach have all worked with Arnold Schwarzenegger. Kull the Conqueror was originally going to be the 3rd Conan film "Conan the Conqueror" with Schwarzenegger reprising the role of Conan the Cimmerian.
While practicing for the fight scenes, Kevin Sorbo nicked himself with a dull-bladed prop sword. At his request, producers gave him a rubber sword.
Kull the Conqueror was originally going to be the 3rd Conan film "Conan The Conqueror" and would be an adaptation of the novel by Robert E. Howard, in which a 45 year old Conan, now King of Aquilonia, learns of a group of conspirator's plot to depose of him, by resurrecting the ancient sorcerer from the pre-Hyborian empire of Acheron, Xaultotun.
In the Finnish translations of the Kull stories, the character name 'Kull' was changed into 'Kall' to avoid unintentional comic elements (there is a Finnish word meaning 'penis' that resembles 'kull' quite a bit). This, however, was not done with this movie, adding its part to the unintentional comedy.
