 Originally planned as a sequel to _Satans Sadists (1969)_ (qv),  with Russ Tamblyn (qv) and other "bikers" reprising their parts  from that film. However, not long after filming began, it was  decided to turn it into a horror film instead of a biker picture and  much of the footage with Tamblyn and other actors from the first  film was cut out. They were unable to cut them completely out of the  movie, though, which is why Tamblyn and his biker gang seem to be  wandering in and out of the film, with no connection to the story  line and with not much to do.
