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, Rovi
Although this isn't as much fun as Murder by Death (or non-Simon films like Clue and Dead Men Don't Wear Plaid), this send-up of Casablanca and Maltese Falcon is still a pleasant watch. Falk, Mason, and Kahn are particularly delightful.
While trying to clear his name of a murder charge Peter Falk also trys to solve a case while having more and more people involved in it show up. The return of a lady love further complicates matters while adding a new twist. One funny turn after another makes you wonder if he'll ever get his name cleared. It has an ending you would not expect, at least I didn't.
