Electronics salesman Bobby Grady (John Laughlin) is hired by a fashion designer to do some nighttime surveillance trailing one of his employees, Joanna Crane (Kathleen Turner) whom he believes is stealing from him. While following Joanna, a serious, no nonsense business woman by day, Bobby is shocked to learn that at night Joanna takes to the streets as China Blue, a sharp tongued prostitute willing to fulfill any fantasy. Bobby, who’s marriage to his high school sweetheart Amy is in shambles, pays Joanna, as China Blue, a personal visit and soon finds himself falling for the real Joanna, all the while Joanna is being relentlessly pursued by reverend Peter Shayne (Anthony Perkins), a psychotic preacher obsessed with “saving” her.
Crimes of Passion is a blunt as a film can be in the way it presents it ideas yet at the same time can still be a bit difficult to get a read on in that while its subject matter is incredibly heavy, this is also a Ken Russell film filled to the brim with bizarre and flamboyant moments. On a purely surface level, this is a film about sex, however deep down its really a film about fear. Bobby’s fear of admitting his marriage has lost whatever spark it may have had, Amy’s fear of admitting her lack of interest in sex and Joanna’s fear of being herself and letting anyone into her life in an intimate manner outside of her China Blue persona. Its these things which give the film its heart, particularly in the dialogue department. The discussions of sex are frank and at times awkward yet purposely so, for instance in a brilliantly performed scene between Bobby and Amy where the two are finally honest with each other for the first time in what seems like ages. On the opposite end of the spectrum would be the back and fourths between China Blue and Reverend Shayne, which are just fierce but also darkly comic and the film does have a tendency to bounce back and forth between being a serious drama, erotic thriller and absurdist comedy and the later takes over every time Perkins is on screen in one of the most hilariously deranged performance ever captured on film.
