A charming film with Matthau giving an oscar-nominated performance as a fifth-wheel grandfather living with his son (Charles Aidman), daughter-in-law (Felicia Farr, aka Mrs. Jack Lemmon), and their infant son, whom Grandpa adores. Lemmon directed his pal Matthau in this film, and look for Lemmon doing a brief cameo as a sleeping bus passenger. Into Kotch's life comes Erica, the babysitter, who is forced to drop out of high school due to an unintended pregnancy, and the two strike up an unorthodox relationship (no, it's not what you're thinking). There is a riotous scene where Kotch delivers the girl's baby in the ladies' room of a gas station, and some "awww" moments throughout the film. One quirk: watch for Kotch to speak German in an Italian restaurant, Spanish in a Swiss restaurant, and French in a Mexican restaurant. Give this one a chance and you'll be rewarded.
