The Heartbreak Kid
After her brilliant career in a comedy duo with Mike Nichols, Elaine May made tentative progress as a director, making only four films between 1971 and 1987 (her last being the disastrous but underrated Ishtar). Released in 1972, The Heartbreak Kid (from a screenplay by Neil Simon) is widely considered her best work from behind the camera, and it's still one of the most accomplished--but least recognized--comedies of the 1970s.
