Cheaper by the Dozen

The Cheaper by the Dozen franchise consists of a series of films and stage adaptations, based on the real-life events of the Gilbreth family. Based on novels co-written by Frank B. Gilbreth, Jr. and Ernestine Gilbreth Carey, the film series includes two biographical films and three loosely-remade family comedy films inspired by their story. The general plot centers around the lives of parents with a large number of children. Each depicts familial relationships, and working through the challenges that arise with an over-sized household.
