Sealab 2021 is an American animated television series shown on Cartoon Network's adult-oriented programming block, Adult Swim. It premiered on December 21, 2000 and the final episode aired on April 25, 2005. Sealab 2021 is one of the four original Williams Street series that premiered on Adult Swim in 2000 (the others are Aqua Teen Hunger Force, The Brak Show, and Harvey Birdman, Attorney at Law).
Like Cartoon Network's Space Ghost Coast to Coast and Harvey Birdman, Attorney at Law, the animation used stock footage from a 1970s Hanna-Barbera cartoon, in this case the short-lived, environmentally themed Sealab 2020, along with original animation. Sealab 2021 was produced by 70/30 Productions.
The year is 2021. Deep below the ocean's surface, looms a vast, magnificently high-tech compound: Sealab. A multi-national scientific station with an annual budget in the trillions, dedicated to the research and exploration of man's final frontier... Sealab's crew is charged with exploring the possibility of underwater colonization. As the Earth's surface, by this time, has gotten just generally crowded, hot, and icky. However, as most government-funded agencies usually are, Sealab is manned by a motley collection of malcontents and screw-ups who were unfit for work in the private sector. They really don't get any research done, but instead spend their time bickering among themselves. Or just plain goofing off. The crew have manipulated their luckless leader, Captain Murphy, into submission, and are content to ride the government clock, raking in fat, hazardous-duty paychecks. Written by Matt Thompson
This is a remake using old animation from Hanna-Barbera's Sealab 2020, which was an educational cartoon about the environment. The premise for Sealab 2021 is that all of the characters have gone insane. Few if any characters on the show would be deemed able to run a trillion-dollar research station, especially Captain Murphy, who is left in charge. The plot of each show is usually absurd, and always hilarious. Written by Anonymous
