‘Cheaper by the Dozen 2’ only has 12 child actors. How could you possibly top that? Well, how does 18 sound? Dennis Quaid and Rene Russo star in the Nickelodeon movie ‘Yours, Mine & Ours,’ which is scheduled for release this holiday season. The flick features Quaid and Russo’s characters getting married and blending their families of eight and 10 into a childish slapstick comedy. And it’s only a matter of time before the little rascals start getting a little too playful.
