The frequent use of split-screen seen in this movie was a necessary editing tool as many of the stunts were filmed on 16mm and as such in order to fill the wide-frame, two images were often co-situated within the film frame.
Director Brian Trenchard-Smith signed the rock group Sorcery after seeing a video-cassette of a performance of the troupe from a 1977 Los Angeles night-club. Brian did see the band at the S.I.R. soundstages in Hollywood to meet the band members for the first time, before shooting started.
According to director Brian Trenchard-Smith, this picture was not intended to be a vehicle for the rock band Sorcery, it was intended to bring Grant Page to the American audiences. Sorcery turned out to be a the best band for the movie.
This movie was made to launch actor-stuntman Grant Page on the international film market. The earlier film Les cascadeurs de la mort (1976) was also intended to do this but due to its failure, this movie took over the mantle.
Brian Trenchard-Smith, this movie's director, once said of the rock troupe Sorcery: "They're so stunt-oriented. Sorcery's seven members created every bit of their act themselves delivering a multi-media assault on the senses that, for the first time, effectively blends rock music with intricate illusions".
