Philip, the Stone Age lord of an elegant cave suite, is something of a Neanderthal when it comes to change. Rumors of a new secret weapon worry him. So does the alarmingly barbaric tribe that has settled across the river who live in boxes made of wooden logs with a panel that opens and closes! Then there's his son, Thomas, who has dropped out of hunting-fishing-agriculture school and does nothing but play with inventions. His daughter, Sharon, befriends animals instead of attracting a nice caveman who will carry her off to a decent cavern in a good neighborhood. Cousin Rudolf arrives riding a monstrous creature that snorts and cavorts. He brings along a new mate, a sturdy Celtic girl of considerable muscle, who is charmed by him for sharing some of the drudge work. It's the dawn of a new age that includes the wheel, running water, beasts of burden, the bow and arrow which can kill from afar, tamed animals you can pet, women who think for themselves, and Philip doesn't like it! How he copes with this whirlwind of change makes for a hilarious Stone Age romp that pokes delicious fun at our contemporary foibles. About 50 minutes.
