What is meant to be going on is not revealed up until the end but by then the various lectures about what subliminal advertising is have unsubtly drained the surprise out of such a denouement. And for all the possibilities inherent in the idea, the film avoids them and concentrates instead on standard thriller tropes – car chases, break-ins and so on. It is drearily directed by tv director George Kaczendar who fails to create any situations that ever generate suspense. The dialogue is all snub-nosed sub-Mickey Spillane quips – “This doctor must be a proctologist – he’s giving me a pain in the ass,” or “They injected me in the butt”, “Turn the other cheek.” The film’s most amusing sequence is where Lee Majors escapes two pursuers by pouting kisses at a group of bikers stopped at a railway crossing, inciting them to attack the car.
