Spoofing the entire 1940s detective genre, and his own performances as a bumbling private detective,
Peter Falk plays Lou Pekinpaugh, a San Francisco private detective accused of murdering his partner at the instigation of his mistress, the partner's wife, Georgia Merkle (
Marsha Mason). Police Lieutenant DiMaggio (
Vic Tayback) has his eye on Lou and blunders around in a way which complicates Lou's efforts to clear his name. Lou gets a new client when Mrs. Montenegro (
Madeline Kahn) and her cronies (John Housman, Paul Williams and
Dom DeLuise) hire him to search out a dozen diamond eggs. Marlene DuChard (
Louise Fletcher) also comes to him for help of a complicated nature. In this madcap comedy written by
Neil Simon, obstacles and complications appear every few minutes, and a great many famous actors show up in hilarious cameos. ~ Clarke Fountain, All Movie Guide
