Whew! That said, let me straighten out a possibly intentional preconception. These sophisticated couples, with an early flirting reference, seem to be playing to the naughty implication of the title. You'll comprehend the title once you've met the kids, because they are the heart of this film. Now a cast including Frederic March, Lilyan Tashman, Kay Francis and Seena Owens giving great performances can't be upstaged, right? Well this batch is the best I've seen. They steal every scene and are given lines which mirror just what you're thinking. And they deliver them like bullets. It's timed like some successful stage play where the comedy has been closely honed in front of an audience. March is doing his job just keeping a straight face!
It all works thanks to a wide open Mary Brian as the oldest (17) of the kids. Her full throttle approach to the role locks all the elements together. She has to work vigorously to keep stability in the kids custodial situation. Indeed, spying on her charges, she discovers them playing Divorce Court.
Director Lothar Mendes loaded the film with brilliant touches. Mary Brian as Judy has a full, puffy coiffure while the other females have close, short hairstyles. The eternally effeminate William Austin's on hand to be Kay Francis' "big, strong (rich) man". Mitzi Green teaches him what its like to be a father, making him her pony. The children interface with adults on adult terms, playing them like violins. I won't disclose some delicious scenes as they should be yours to discover. Have fun!
