A 1976 BlackComedy, directed by Creator/AlfredHitchcock. It was his last film. The main cast included Barbara Harris, Creator/BruceDern, Karen Black, and William Devane.
The film starts with a SpookySeance contacted by Blanche Tyler (Harris). Her latest client is elderly Julia Rainbird (Cathleen Nesbitt), who wants to locate her last living relative. Said relative being the illegitimate son of her sister, given for adoption decades ago. Now that boy is supposed to inherite the family fortune. Julia offers Blanche 10,000 dollars to find her heir. Blanche is actually a PhonyPsychic. The facts she reports to her clients are the results of some detective work by her boyfriend. Said boyfriend, George Lumley (Dern), is an unemployed actor and part-time cab driver. The two bumbling detectives now have proper motivation to find that heir.
The scene shift to the heir Arthur Adamson (Devane) and his girlfriend Fran (Black). They are both WickedCultured. Arthur murdered his foster parents many years before. He works as a jeweler and upper-class house. He and Fran actually earn most of their money from a highly-successful career as kidnappers. Their targets being millionaires and dignitaries. By the time the film starts, the thrill of the work has become part of their motivation. Danger turns them on and really helps their sexual activities. These two are dangerous people.
Naturally, seeking out the two master criminals turns out to be a more dangerous mission than Blanche and George expected.
