Original Run: 130 episodes (January 23, 1985 – September 29, 1989)
Premise: A team of feline-like humanoids fight mutant creatures and ancient sorcerer Mumm-Ra for control of Third Earth.
Why It Could Work: A ThunderCats feature film has been in the works for years - with the most recent (cancelled) version relying on CGI animation to bring the characters to life. Still, while Hollywood has struggled to adapt the characters, there's plenty of reason to think that a ThunderCats film could work, given the right approach. A live-action attempt would be challenging but, if the visual effects team succeeded in making the ThunderCats, Mutants of Plun-Darr, and Mumm-Ra look cool (not campy), the characters offer plenty of room for filmmakers to deliver slick fight choreography and cool vehicular (i.e. ThunderTank) action. Additionally, as James McAvoy recently pointed out, Lion-O is actually a twelve-year old trapped in the body of a ripped, muscly, fighting man who is destined to be king - laying the foundation for a unique hero tale.
