This week’s minorities in cartoons entry is “Sealab 2020,” a Hanna-Barbera animated series that aired from 1972 to 1973 on NBC.


The series focused on the 250 residents of an undersea scientific research facility in the then-far-off year 2020; said facility was headed by Captain Michael Murphy. Plots usually revolved around underwater threats and challenges, including dealing with sea creatures, endangered species, ecological and man-made disasters, and other problems.

The show reflected its early 70s origins, when the modern ecology movement had started to gain steam. It also reflects lingering 60s pop cultural interest in the Earth’s oceans (see: Aquaman’s Saturday morning series, “Voyage to the Bottom of the Sea,” etc.).

The series saw 15 episodes produced (two supposedly unaired per Wikipedia), and ran its course. However, from 2001-2005, it was revived as an Adult Swim parody called “Sealab 2021.” It had zero in common with the original series, but plenty with shows like “Aqua Teen Hunger Force” and “Harvey Birdman.” Like those two shows, “2021” saw the main cast as largely sociopaths, insane, selfish jerks, or idiots.

“Sealab 2020” featured an African-American scientist named Ed (no last name apparently given). Comedic spinoff “2021” featured a retooled version of the character named Quentin Quinn. “2021” also specifically featured a scientist (of vague Latino heritage) named Marco (full name: Marco Rodrigo Diaz de Vivar Gabriel Garcia Marquez).

Voice actors

Ron Pinkard voiced Ed. Pinkard’s an African-American actor in such 70s TV shows as “Emergency!”

Brett Butler voiced Quinn. Butler’s IMDB credits are heavily for audio production/editing, though Wikipedia (what little it has) says he’s also done some stage productions.

Marco was voiced by actor Erik Estrada, most famous for starring on 70s cop show “CHiPs.”

On TV/home video

Both “2020” and “2021” have all of their episodes available on DVD sets, the former via the Warner Archive service.
