NBC had a potent lineup in 1981. The Smurfs were introduced to American audiences for the first time. The rest of the lineup, however, was dominated by superheroes for the first time in years. Space Stars was supposed to have aired a year earlier, but was held back because of a writer's strike in Hollywood. The series marked the returns of two of Hanna-Barbera's super adventure series of the 60's, Space Ghost and the Herculoids, plus two new features, Teen Force and a spin-off from The Jetsons, Astro & the Space Mutts. Superherocartoonsite uploaded the open, narrated by Michael Rye (the voice of Green Lantern & Apache Chief on Super Friends):
Unfortunately, there are no Teen Force episodes available on YouTube at present, largely because when Space Stars aired on USA in the late 80's, the segment was deleted from the show, along with Astro & the Space Mutts, for time constraints, more than anything else. The Force, however, would frequently team with Space Ghost, and that was largely due to Kid Comet dating Jan, one of Space Ghost's proteges. You wonder why they didn't try to complete the double date and have Jace paired with Elektra. Boomerang & Cartoon Network have ignored the Teen Force as well, and it's their 30th anniversary year!
Actor Keene Curtis (ex-The Magician, later of Cheers) served as the narrator for all the segments, and to my knowledge it's his only cartoon credit. Regrettably, Space Stars was cancelled after 1 season, and NBC replaced it with The Incredible Hulk the next year, among others. A pity, considering the lack of respect accorded the Teen Force since.
