23. Family Plot (1976)
Stars: Barbara Harris, Bruce Dern, Karen Black, William Devane, Cathleen Nesbitt, Ed Lauter, Katherine Helmond, Nicholas Colasanto
Released four years before Alfred Hitchcock's death in 1980, Family Plot was the prolific director's final movie, and, fortunately, he went out on a high note. Adapting author Victor Canning's novel The Rainbird Pattern, Hitch, despite being 77 at the time, clearly had a blast making his big-screen swan song, maneuvering around a somewhat convoluted and twisty plot—about a couple of con artists who cross paths with a pair of serial kidnappers—with a delightfully morbid sense of humor (a few of the film's funniest moments take place in cemeteries, for instance).
