ST is one of the more emotionally intense of the late golden age films, and does a fine job of combining sex with a sinister, edgy kind of Cronenberg mentality. Paul Thomas is the head of a sex therapy institute, and is cracking up. He is obsessed with therapist Annette Haven, and in a series of recurring fantasies, he dreams of Miss Haven, dressed in Skintight black leather, in a nightmare setting of shadowy sexual activity. Lisa Deleuw also inhabits this fantasy realm. Thomas is already in a bitter confused state because of unusual sexual problems with his wife, and when Haven (also the victim of Thomas’ recurring obscene phone calls) leaves to get married, Thomas snaps completely. The theme of someone going mad is a frequent one in adult films because it lends itself to frequent imaginary or hallucinatory passages, thus allowing a lot of sex scenes. This particular portrayal is effective because Paul Thomas isn’t a bad actor – he played Peter in the 1973 Norman Jewison JESUS CHRIST SUPERSTAR, which is a pretty good credit for a porn actor’s resume.
