This last Hitchcock film may seem out of step with all of the others, but then it has to be. The sexual/cultural revolution is over. The cynical 70s are in full swing. You can't just insinuate "the act" anymore and cut to the seashore.
Into this environment comes "Family Plot". It is basically two sets of crimes, one minor and one major, hitting an intersection with one group of criminals having no idea what the other group is up to.
Blanche Tyler (Barbara Harris) is a fake psychic. She has her cabbie boyfriend get information for her based on the hints she gets from the séances. In this case a wealthy woman, Julia Rainbird, claims her sister's spirit and her own conscience torment her because in 1933 she made her sister put her illegitimate child up for adoption because of the scandal that would have occurred given the conventions of the times. Nobody knows what happened to him since the adoption was closed. Now Julia Rainbird, in her old age, wants to accept her nephew into the family and leave the entire estate to him. There is 10K in it for Blanche if she can find him.
What Blanche and cabbie lover George (Bruce Dern) don't know is that the long lost heir is basically Lex Luther with hair - William Devane as Arthur Adamson, a true sociopath who loves thumbing his nose at conventions and loves crime. Together he and his girlfriend, Fran (Karen Black) kidnap wealthy people in exchange for jewels. Adamson has a legitimate business as a jeweler as a front.
The misunderstandings come in when Adamson discovers that somebody is digging into his past, specifically his faked death which was a cover for the murder of his adoptive parents back in 1950. Blanche and George can't figure out why they would be getting attempts on their life. Adamson has no idea of his true identity and has no idea why these two amateurs are trying to find him, figuring it has either to do with his current kidnappings or the past murder of his parents.
It all comes together in a suspenseful and comical way. I'll let you watch and find out how.
Blanche and George are a hilarious couple just perfect for 1975. In one scene, at the end of the day, she is basically ordering him to come inside the house and sexually service her. George replies she is wearing him out and he has to work tomorrow. She asks "what are you saving it for?". This is a long way from the stolen glances, passionate kisses, and hand holding in "Dial M For Murder", but this is a different time and they are just right for it.
Even at the end Hitchcock did know how to change with the times. I'd recommend it.
