Did You Know?


Lucio Fulci and Roberto Gianviti's script originally took place in Louisiana (the setting of Fulci's later film The Beyond (1981)), and featured a symbolic pre-title sequence that was to be shot in the state's trademark wetlands, depicting a garden spider ensnaring a locust in its web and eating it, leaving only its shell. It was rewritten to take place in San Francisco as a cost-saving measure due to producer Edmondo Amati wanting to have the film shot back-to-back with another film he was producing, Carnal Circuit (1969), the exteriors for which were shot in Los Angeles. Similarly, George was originally written to have his death sentence carried out via electric chair, but due to the location shift, this was changed to the infamous gas chamber in San Quentin Prison in which Caryl Chessman had been killed, a fact especially highlighted by the film's trailer, which stated that much of the prison staff responsible for Chessman's execution "reprised" their roles for the film. These alterations were likely implemented into the script by assistant director Massimo Castellani, Franco Ferrari and Massimo Franciosa, who were credited on the film's budget sheet but not in the onscreen credits.

San Luis Obispo is due south of San Francisco, but to get there from San Francisco George is seen driving over and past landmarks taking him east of his destination such as the San Mateo Bridge or north of his starting point such as the Golden Gate Bridge. See more »


Monica Weston: [about to have sex with George] I hope you didn't mind being alone for a few minutes. I wanted to change into something nice; I think making love should be elegant, yet simple. You know... me and you. Nothing elaborate.
Dr. George Dumurrier: You don't go for threesomes?
Monica Weston: Depends on how much I get.

User Reviews

Fulci's best-ever 'pensioners in titty bar' movie
5 March 2010 | by DanielKingSee all my reviews

Pretty decent stab at an erotic thriller from the Goremeister General. It's all the things you would want: stylish, sexy, and gripping. It's also crisply shot and has an excellent Riz Ortolani score. Again, the dubbing is pretty ropey but if, by this point, you're seeking out some of Fulci's lesser-known works then it's safe to assume you've made your peace with this constant problem.

Marissa Mell is great as the femme fatale and Elsa Martinelli is cool and chic as the devoted mistress who, despite herself, can't stop believing in her man. In fact, the female performances are much stronger than the men, probably because Jean Sorel doesn't have much to do except wander around with his shirt off, looking bewildered.

Great photography of San Francisco, looking as good - if not better - than in BULLITT. There's also a fine cameo from Jean Sobieski, for connoisseurs of louche photographers in movies.

The only real problem is that the film isn't quite gripping enough. The premise is set up well in the first half hour or so, and the suspense and mystery sustained during the kinky interludes in the middle, but all is revealed through a clumsy expository scene with about 20 minutes remaining and after that it runs out of steam.

Well worth a look though.
