Marilyn Monroe, Cary Grant and Ginger Rogers star in this classic comedy about a chemist who discovers the secret of eternal youth. For years Dr. Barnaby Fulton (Grant) has been working on a youth-restoring serum with little success, until the day a chimpanzee gets loose in the lab and accidentally concocts the exact formula Fulton has been searching for. The hilarity begins when, unbeknownst to anyone, the chimpanzee pours it into the office water cooler. With each successive drink, everyone gets younger and younger. When Fulton's stunning secretary Lois (Monroe) and his lovely wife Edwina (Rogers) get a taste of the potion, the chemical reaction is explosive and hilarious fun!
