Cheaper by the Dozen
Steve Martin, Bonnie Hunt, Eugene Levy
It is actually Cheaper by the Dozen 2 - not counting the previous films on a similar theme from long ago - since it continues the Martin-Hunt partnership, along with their clutch of children.
This time they're on vacation and locked in a slapstick competition with Levy's family. The plot really doesn't count for much since the pratfall comedy is everything.
Happily there is no overt family sentimentality in the film which allows you to merely sit back, relax from the Yuletide shopping and enjoy and it's better than the first one, with Martin in particularly good form.
