Sealab 2020 (1972) - Opening (Spanish)

Much of you wil surely know the hilarious cartoon ''Sealab 2021'' at Adult Swim. This is the original series which was re-edited and parodied. The series was about an underwater research base and had an environmental theme. The series ran on NBC in 1972 and was canceled after only thirteen half-hour episodes (perhaps for the boring plot). This show has not been released on DVD.
