September 23, 2006 - Added plot synopses for all of the episodes.   These are actually the synopses Magic Shadows provides in the syndication package for Captain Nemo.

July 19, 2006 - Al Guest and Jean Mathieson contacted me recently by email, and provided some more information about The Undersea Adventures of Captain Nemo.  They mentioned that their company, Magic Shadows Inc.,  still sells the Nemo shows around the world.   


Question:  What are the Undersea Adventures of Captain Nemo?

Short Answer:   A series of five minute cartoons produced in Canada in the mid-1970's.  They told the story of Captain Mark Nemo and his young assistants, Christine and Robbie, in their nuclear powered submarine, the Nautilus. 

And the Longer Answer..

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 which ran on the CBC.  

Created by Al Guest and Jean Mathieson, (who directed, wrote and produced the show) and produced by Rainbow Animation of Toronto, Ontario, Canada, The Undersea Adventures of Captain Nemo was a fanciful spin on the original Jules Verne character from his book 20,000 Leagues Under the Sea.  

This time, the Captain is re-imagined as a ocean researcher and do-gooder named Mark Nemo.  Blonde and hunky, Mark traveled the world's oceans doing scientific research and thwarting evil doers.  Along for the ride came two kids Chris (short for 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) but as a child growing up in British Columbia I loved them.  Often, if a program ended early on the CBC, and there weren't enough ads or public service announcements to fill the space, an unscheduled Captain Nemo episode would be run, which was always a nice surprise for me.

In the subsequent years, the series has been sold to television stations all across the globe. In particular, it attracted a huge following in Brazil, where it was used to fill in the extra time for shorter soccer games.  In fact, since its first airing, The Undersea Adventures of Captain Nemo was never been off the air - it is always playing somewhere in the world.

At least in part educational, these cartoons are an insight into some of the philosophy around children's education of the mid 70's.  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 1970's environmental movement, but the sometimes clumsy attempts to convey environmentalist themes are softened by its lighthearted style.  

From time to time, the episodes draw from other sources.   For example the episode "The Sunken Fleet of Truk Lagoon" appears to find its inspiration in the 1971 National Geographic documentary about the same area, depicting the exploration of Truk Lagoon by the renowned French oceanographer Jacques Cousteau.

Sometimes cheezy, sometimes a little preachy, but always fun, that's the Undersea Adventures of Captain Nemo.   Here then is a small web presence to play tribute to this show which brought me so much joy as a kid.   Enjoy.

Voice Talent

Len Carlson and Billie Mae Richards

Yep - all the voices in the series were done by these two actors!

Here's a link to Len Carlson's entry on the Internet Movie Database.    Most recently, you may know him as the voice of Minimus PU on the Atomic Betty cartoon.  (I'm also convinced he used his Mark Nemo voice for announcing in ads for Kraft Canada in the 70's, but can find no source to back me up.)

Here's a link to Billie Mae Richard's entry on the Internet Movie Database.   She is most well known for providing the voice of Rudolph the Red Nosed Reindeer in the Rankin Bass Christmas specials.  (You may notice Robby sounds a wee bit like Rudolph sometimes.)   Billie is in her mid-80's these days, but from all reports is still alive and well and living in the Toronto area.

Both these actors also worked on the classic 1960's animated Spider-Man series.




Captain Mark Nemo




















The Nautilus

This cool submarine was the un-credited star of the show.   Futuristic and sleek, with two viewing bubbles on the top, the Nautilus was constructed of a non-magnetic alloy.  Extremely fast, this sub could get from one side of the world to another within a single five minute episode.

Some of the equipment on the Nautilus included:

- jet propulsion

- external television cameras which can be easily monitored from the bridge

- accurate long range sonar 

- "surface scan" which could show visually what was happening on the surface of the ocean

- airlock system

- shark cage

- search lights

- global videoconferencing, even from deep in the ocean

- a two person mini-sub which could be launched when the Nautilus is submerged

- a computer library system which a robotic sounding voice readout

- laser guns with the power to weld metal together underwater from a fair distance

- torpedoes

- a harpoon gun and netting system

- powerful pumps which could discharge huge amounts of fresh water

Peanuts and Popcorn 

In 1975, the Canadian Broadcasting Corporation (CBC) moved into children's programming on Saturday mornings with a ninety minute package of films. The program was called Peanuts and Popcorn, and included a cartoon, a serial, and a one hour film. 

The main Canadian component of the program were The Undersea Adventures of Captain Nemo animated shorts, produced by Rainbow Animation Ltd. of Toronto. 

The whole Peanuts and Popcorn series was coordinated by Nada Harcourt (l975-77) and Suzanne Garland (l977-78).

The original airdates of Peanuts and Popcorn were:

Sat 10:30-12:00 noon, 4 Oct 1975-27 Mar 1976

Sat 10:30-12:00 noon, 2 Oct 1976-26 Mar 1977

Sat 10:30-12:00 noon, 1 Oct 1977-25 Mar 1978

Sun 11:00-12:00 noon, 7 Oct 1978-31 Mar 1979

New Life on DVD

In 2005, Digiview Productions, a producer of inexpensive DVDs, released the Captain Nemo cartoons in a series of four volumes.   These were chiefly made available through Walmart where each DVD, containing 12 episodes of the show, retailed for $1.00 a piece. I bought them, of course, and found the transfer quality to be excellent.   Be careful in selecting from the Walmart bargain bins though - sometimes the ones toward the bottom can be a little beat up.

An online review of the Captain Nemo DVDs can be found here.



Frequently Asked Questions

(in this area I will post questions I receive from interested visitors)


October 15, 2005 - - Question:   Is there any connection between The Undersea Adventures of Captain Nemo and the animated series Rocket Robin Hood?

Yes.   Al Guest and Jean Mathieson, the creators/directors/writers/producers of Captain Nemo, worked on both series.   Trillium Productions, based in Toronto, Ontario, made Rocket Robin Hood. Trillium was part of the Guest Group, a group of creative companies owned and run by Al Guest, who was somewhat of a legend in Canadian broadcasting circles in the 1970's.    He also produced Captain Nemo.   Jean Mathieson was a key animator of Rocket Robin Hood, particularly in the first and season seasons.   Jean was also notable as one of the first woman animators.  She went on with Al Guest to form Rainbow Animation in Toronto, which produced Nemo, and for that show she had a variety of duties, including animation supervisor.    She also formed Magic Shadows Inc. in the United States with Al Guest.

Finally, the voice of the character Rocket Robin Hood in the 1968-1969 season is that of Len Carlson, who provided the voice for Mark Nemo.


October 15, 2005 - - Question:   When does The Undersea Adventures of Captain Nemo take place?

A good question.  Although this is never quite established in the series, it can be surmised that Captain Nemo takes place in the near future.   

Technology, such as that of the Nautilus, and the presence of the United World Organization which runs a global governmental agency that protects the world's oceans appear to be evidence of that.   Like many near future worlds envisioned in the 1970's, I think it's safe to say it was supposed to take place around the year 2000.    (sidebar:  Sealab fans of course suggest the year 2020, or even better 2021).

Interestingly, one of the futuristic items mentioned in Captain Nemo is a ban on commercial whaling.   In reality, a moratorium was established on commercial whaling by the International Whaling Commission in 1986.
