Watching serial killer Christopher Gill (Rod Steiger) trying to enlist the trust of his prospective victims is what makes this film really interesting. Once these babes in the Manhattan woods let down their guard, then ... pounce. And like some deep-sea predator that changes its color or its shape to suit the needs of its prey, Gill changes his disguise from Irish priest to plumber to eccentric hair stylist to waiter, to suit the needs and desires of his selected middle aged female targets.
Gill is a loner, but he still needs human contact. So, between killings, he engages in a phone dialogue with detective Morris Brummel (played well by George Segal). Gill also checks the newspapers frequently, to verify that his killings get noticed by the police and by society in general. The film is thus a character study of a fictional psychopath. But the characterization is consistent with expert profiling of the generalized needs and motivations of real life serial killers.
Indeed, some researchers have speculated that the infamous Zodiac killer "may" have studied this film. In some ways, Gill's modus operandi is similar to that of the Zodiac who was known to be a movie buff. Further, the killings in the San Francisco Bay Area premiered just a couple of years after this film came out.
Quite aside from its possible historical significance, the film is very well made. It conveys a well-written script, good cinematography, attention to detail in costumes and production design, effective pacing and editing. The background music at the film's beginning and end is beautifully haunting, and lends a tone of sadness, and therefore emotional depth, to the story. And, of course, Steiger's performance is so good that it alone makes the film worth watching. The only downside is Morris Brummel's nagging mother who quickly becomes grating and irritating.
That this film has been largely forgotten is unfortunate. But it is available on DVD, and therefore can be seen by anyone who appreciates good movies.
