"This is the year two thousand and twenty. The place is the Challenger Sea Mount, the top of an underwater mountain, a complex beneath the sea. Two hundred and fifty men, women and children live here. Each of them, a scientist pioneer. For this is our last frontier, a hostile environment which may hold the key to tomorrow. Each day, these oceanauts meet new challenges as they build their city beneath the sea. This is Sealab 2020." With these words setting the stage, and some funky bass riffs setting the tone, Saturday morning TV took the 70s underwater Sci Fi adventure plunge. Ably overseen by Hanna-Barbera's ace action animators and voiced by a superb cast (including John Stephenson, Ross Martin, Jerry Dexter and Ann Jillian), the oceanauts of Sealab face seaquakes, sharks and falling satellites while finding the time to serve up lessons on environmentalism, tolerance, and teamwork across this 2-Disc, 13-Episode Collection
