It's not an all-timer, but Family Plot is a fun, seedy romp that shows off Hitchcock's genre range.
This was the final feature film of Hitchcock's career, and it is an interesting last project, as Family Plot is a dark comedy with hints of suspense thrown in for good measure. An elderly woman hires Blanche (Barbara Harris), a slightly shady psychic, and George (Bruce Dern), Blanche's very shady boyfriend, to track down Arthur (William Devane), her long lost nephew. They're able to locate Arthur, but he's a bit of a scoundrel himself and assumes the two have more nefarious reasons for tailing him. It's not an all-timer, but Family Plot is a fun, seedy romp that shows off Hitchcock's genre range.
