Yours, Mine, and Ours(2005)
A remake of the classic 1968 film. High school sweethearts Frank Beardsley, a widowed Coast Guard Admiral and Helen White, a widowed handbag designer, get re-united after Frank and his family of eight kids move into the neighborhood. Even with Helen and her ten kids, some biological and some adopted, the two quickly decide to marry in a private ceremony, and the large family with 18 kids can't seem to get along. Frank has a very regimented and scheduled view of life while Helen is more outgoing and free-thinking, and this model has rubbed off on their respective kids. Now, this big family must learn to put aside their differences and learn to come together as the family they are.
