Yours, Mine & Ours (2005)

Frank Beardsley, a Coast Guard admiral with eight children, and Helen North, a designer with ten children, reunite on their 30th high school anniversary and the spark between them is evident. Having widowhood in common, they fall in love and move in with their children: all 20 living together in the same house. With different parenting styles, they soon crash into each other. This remake of a 1968 comedy has guaranteed laughs and romance thanks to the chemistry between Dennis Quaid and Rene Russo.
