Age of Resistance begins way before the events of 1982's 90-minute Dark Crystal, and expands on the story in 10 hour-long episodes. If you don't recall, or have never seen the original (which is conveniently available to stream on Netflix), it begins with the elf-like Gelfling Jen, who has been living with a kindly tribe of Mystics, sent on a quest to retrieve a shard of the Dark Crystal, which, when broken, brought the Mystics and their evil, greedy counterparts the Skeksis into the world of Thra.
When it was released, the movie mostly perplexed people who were only familiar with Jim Henson through his family-friendly Muppets -- a far cry from this dark, frightening tale. (It also had the misfortune of going up against Steven Spielberg's E.T. at the box office, a fate I wouldn't wish on most movies.) But, through the years, as these things tend to do, the small fandom grew into a sizable cult.
"We're in the cult! It's The Dark Crystal, for God's sake!" Grillo-Marxuach said. "How often, if your name isn't J.J. Abrams, you get to go and, like, work in the footsteps of people who are giants from your childhood who literally informed your experience of the world?" Addiss, who used to sketch Mystics in his notebook, had actually once made one for a class project -- and took twice as long as the other students to complete it: "Everybody else in the class had moved on to the next project, but I said no."
