The Facts of Life (film)

The Facts of Life is a 1960 romantic comedy starring Bob Hope and Lucille Ball as married people who have an affair. Written, directed, and produced by the longtime Hope associates Melvin Frank and Norman Panama, it was more serious than many other contemporary Hope vehicles.

As the yearly vacation of six neighbors, the Gilberts, Masons, and Weavers, approaches, Kitty Weaver Lucille Ball and Larry Gilbert Bob Hope find themselves frustrated with the routine. When both their spouses Ruth Hussey and Don DeFore are kept away from the vacation, Kitty and Larry find themselves alone in Acapulco, with the Masons Philip Ober and Marianne Stewart bedridden with illness. Forced together, Kitty and Larry fall in love. Once the vacation is over, however, they have difficulties in either abandoning or continuing their romance.
