Adam Reed and Matt Thompson, the creators and writers of Sealab 2021, came up with the idea for the show in 1995 while they were production assistants for Cartoon Network. They stumbled on a tape of the show Sealab 2020, and wrote new dialogue. Cartoon Network passed on the show because they did not believe it was funny. Five years after quitting Cartoon Network, the two went back to the original tape, this time making the characters do what they wanted. Cartoon Network bought the show, coincidentally around the same time that Adult Swim was created. The original "pitch pilot" is available on the Season 1 DVD as a special feature.
