Here’s one…
Yours Mine & Ours.
Rated PG. A 2005 remake of the 1968 classic that starred Henry Fonda and Lucille Ball, and the story is basically the same: Widowed man with eight children meets widowed woman with 10 children. Eventually, all 18 kids learn to live as one big happy family, but not before driving their respective stepparents and each other to the brink of crazy. The rest are here.
EDIT – I placed a pic of the original, because it’s better.
