Hello Down There (1969) - DVD

When an inventor (Tony Randall) needs human guinea pigs to test his experimental undersea dream home, he packs up his wife (Janet Leigh), his kids and their rock and roll band and takes the plunge. While this average – if extended – family adapts to life on the ocean floor, the band must find a way to get its groovy new single into the hands of a top record producer before it’s too late. Our aquanauts are in for even more deep trouble when greedy prospectors, hungry sharks, a hurricane and a battle-ready U.S. Navy threaten to turn their happy underwater home into a real bummer!
