San Diego Junior Theatre's cast of Cheaper by the Dozen, based on a biographical novel written by Frank Bunker Gilbreth, Jr. and Ernestine Gilbreth Carey, published in 1948. It tells the story of efficiency experts Frank Bunker Gilbreth and Lillian Moller Gilbreth, and their twelve children. The book was adapted to film by Twentieth Century Fox in 1950. The 2003 and 2005 films bear little resemblance to the original book or 1950 film.
