The Undersea Adventures of Captain Nemo is a Canadian animated television series of five-minute cartoons produced in 1975 by Rainbow Animation in Toronto, Ontario. The series follows the underwater adventures of Captain Mark Nemo and his two young assistants, Christine and Robbie, in their nuclear-powered submarine, the Nautilus.^[1]

In the fall of 1975, children in the United States and Canada were introduced to the animated series The Undersea Adventures of Captain Nemo. In America, Captain Nemo was introduced as part of the long-running children's program Captain Kangaroo on CBS. In Canada, one five-minute Captain Nemo cartoon was shown during each episode of Peanuts and Popcorn on CBC Television. The series ran in Quebec as Capitaine Marc Simon.

Created by Al Guest & Jean Mathieson, who were also the producers and directors as well as writers, it was produced by their studio, Rainbow Animation of Toronto, Ontario, Canada. The Undersea Adventures of Captain Nemo was a fanciful re-imagining of the original Jules Verne character Captain Nemo, from his 1870 novel Twenty Thousand Leagues Under the Seas.

This time, Nemo was depicted as an ocean researcher named Mark Nemo. Blond and hunky, Mark travelled the world's oceans doing scientific research, providing assistance to both humans and animals and thwarting evildoers. Along for the ride were two kids, Christine and Robbie, who learned (along with the viewers) about life beneath the sea as they went.

These cartoons were quite short, exactly five minutes in length (30 seconds of which was the opening). Besides being educational, these cartoons are an insight into some of the philosophy around children's education of the mid-1970s. Each episode would attempt to convey some information about oceanography or marine biology, and all of the plot lines would be resolved cleanly in five minutes without resorting to much violence.

At times, Captain Nemo reflects the influence of the 1970s environmental movement, but the sometimes serious attempts to convey environmentalist themes are softened by its lighthearted style.
