Longtime fans of the cult TV show Mystery Science Theater 3000 know that the series’ one constant is change (well, that and bad movies).
The show’s cast and crew were in a near-constant state of flux, a byproduct of the show's existence as a perennial bubble show produced in the Twin Cities rather than a TV-and-comedy hub like New York or LA. It was rare, especially toward the middle of its 10-season original run on national TV, for the performers in front of the camera (and the writers’ room, since they were all the same people) to stay the same for more than a season or two.
Series creator Joel Hodgson embraced that spirit of change for the show's Kickstarter-funded, Netflix-aired revival in the mid-2010s, featuring a brand-new cast and mostly new writers. And that change only accelerated in the show's brief post-Netflix "Gizmoplex" era, which featured a revolving cast of performers that could change from episode to episode. Hodgson leaned into the idea that as long as there were silhouettes and puppets talking in front of a bad movie, it didn't matter much who was doing the talking.
