Family Plot was Hitchcock's last film before he became too ill to work, and it's a cheeky romp of a thriller about a "psychic" who promises to find a rich woman's lost heir, her con man boyfriend who actually does the work, and a couple of kidnappers, one of which is that heir. In other words, the heir has many reasons NOT to be found, and no inkling they just want to hand him a fortune, rich ground on which to sow the seeds of misunderstandings and suspense. It's not serious enough to be one of the greats I suppose, but there's lots to love, especially the crazy car chase at the center of the film. As exciting as it is ridiculous.

A pleasant surprise, considering the uneven quality of post-Marnie Hitchcock.

I agree, but not a single dull moment.
