Mighty Mouse: Here He Comes To Save The Day

Mighty Mouse Playhouse first aired on CBS Saturday mornings, beginning December 10, 1955. That date is important because the show helped put the idea of Saturday morning cartoons on the map.

Mighty Mouse had actually started earlier in theatrical cartoons from Terrytoons, debuting in the 1942 short The Mouse of Tomorrow. But TV is what made him a household name. CBS repackaged the older Mighty Mouse cartoons for television, and suddenly kids could see him right at home instead of at the movie theater.

The show had everything kids loved: a tiny hero with super strength, flying rescues, villains, danger, and that unforgettable theme line: “Here I come to save the day!” Mighty Mouse usually showed up just in time to save the helpless and defeat the bad guys.

Looking back, Mighty Mouse Playhouse feels simple now, but it was a big deal. It helped prove that Saturday morning could belong to kids, cereal bowls, pajamas, and cartoons.

CBS Cartoon Theatre

CBS Cartoon Theatre was a short-lived CBS cartoon showcase from 1956, best remembered today because it was hosted by a young Dick Van Dyke before The Dick Van Dyke Show made him a household name.

CBS had bought the Terrytoons library in the mid-1950s, which gave them characters like Mighty Mouse, Heckle and Jeckle, Gandy Goose, and other theatrical cartoons they could repackage for television. CBS Cartoon Theatre was basically a way to put those cartoons on TV with a friendly live-action host wrapping around them. IMDb describes it as a CBS summer replacement show built around the newly acquired Terrytoons cartoons.

What makes it interesting is that CBS tried it in prime time, not just Saturday morning. A TV-history write-up says the show debuted on June 13, 1956, airing in the early evening in some markets, with Dick Van Dyke hosting.

Looking back, it feels like a bridge between old theatrical cartoons and the Saturday morning cartoon era. These weren’t originally made as “TV cartoons.” They were movie-theater shorts being recycled for a new generation sitting in the living room.

The fun part is seeing Dick Van Dyke in that early host role. CBS apparently had him under contract and was still figuring out what to do with him. A few years later, of course, everyone knew exactly what to do with him.
