I see this a lot.
Roger Ramjet is
not related to Bullwinkle at all. However, it's been said that Bullwinkle's Bill Scott was a fan of this series.
But hold on to your hat. This show may not have any Bullwinkle connections, but it does have some concerning something we all should know. Sesame Street!
Hubba Whah you may ask?
The cartoon was really produced by Pantomime Pictures. I'm 90% sure either they or the animation staff would go on to produce early Sesame Street cartoons. But one credit on the show stands out. Jim Thurman. A name to know on Sesame Street. He was both a writer and voice actor for the series. The Sesame Workshop connection doesn't end there. An expy of Roger from the creators of that old series was made for Square One Television. In fact, it's basically Roger Ramjet with math thrown in...
Same exact humor and voice actors too. Gary Owens plays the hero, and Joan Gerber appears as additional voices.
