In May 2019, production began on the series, after
Arnold Schwarzenegger was cast in the lead role as Arnold Armstrong / Captain Fantastic. He served as a co-executive producer with
Paul Wachter,
CEO of Main Street Advisors, and
Fabian Nicieza, who also developed the series. On June 20, 2020,
John Landis signed on to direct and executive produce all of the episodes. The season was to consist of 52 episodes. In July 2020,
Genius Brands and
Archie Comics published the late
Stan Lee's comic book
Superhero Kindergarten, in a multi-year partnership agreement. As with other adaptations of his works, Lee made several cameo appearances in the series. The series was the last project Lee personally worked on. Discussing his work on the series, lead actor Arnold Schwarzenegger said, "
Superhero Kindergarten is near and dear to my heart, the greatest superhero to ever live. What an honor it was to collaborate with Stan Lee on the creation of the series, and I am absolutely thrilled that our new series has resonated so strongly with audiences right out of the gate". Schwarzenegger reiterated this in a May 2021 interview on
The Kelly Clarkson Show, while adding that Stan Lee told him "[he had] an idea for an animated show. What about
Superhero Kindergarten, where you're a kindergarten teacher for kids who have superpowers? You have been a superhero yourself (in the show) but you're now retired and teaching those kids how to be good contributors and how to save the world in the future". ==Episodes==
