The Mothers-In-Law (1967)

The Hubbards and Buells are the best of friends despite their wildly different lifestyles. Herb Hubbard is a successful lawyer and Eve is a former champion athlete, while Roger Buell is a television writer and his wife Kaye is a poor housekeeper to the point of being lazy. Also, Roger and Kaye's son Jerry was married to Herb and Eve's daughter Susie. Sometimes the friendship is tested as both "mothers-in-law" try to help their children as they go through the early stages of their marriage.
