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.
