Barnaby Fulton is a research chemist working on a fountain of youth pill for a chemical company. While trying a sample dose on himself, he accidentally gets a dose of a mixture added to the water cooler and believes his potion is what is working. The mixture temporarily causes him to feel and act like a teenager, including correcting his vision. When his wife gets a dose that is even larger, she regresses even further into her childhood. When an old boyfriend meets her in this state, he believes that her never wanting to see him again means a divorce and a chance for him. Written by John Vogel <jlvogel@comcast.net>

Did You Know?


The address that Edwina gives when she calls the police was Ginger Rogers' real-life address: 1605 Gilcrest. See more »


When Barnaby and Edwina emerge from his office to see that Oxley and the other scientists are behaving like children, a panel in the 'wall' to the right of the door moves, and a gap can clearly be seen in the wall of the set looking into his office.

However, the panel.can be seen to be nothing more than blinds on the office windows. Indeed, they are seen to be open just moments before and were obviously closed to help the baby to sleep. See more »

Very funny
13 May 2002 | by The Movie BuffSee all my reviews

This movie contains a part that is one of the funniest I have ever seen. It is when Cary Grant and Ginger Rogers get called into the board of directors room and they both are acting like children, having both taken the formula without knowing it. To top it all off, the monkey was on the ceiling throwing light bulbs.

Overall it was a very funny movie, clever, yet far-fetched. I would rate this as one of Cary Grants best performances. Ginger Rogers was also very good. However for some reason there wasnt enough Marilyn in this movie. I few parts that she was in, she was very funny. I don't know why she only played a small role in this movie. Her funniest line was at the beginning when the boss told her to go to every ford dealership and look for Barnaby. Her reply was, "Which one do you want me to do first."

It was a funny movie with parts that will have you on the floor.
