Netflix is reportedly planning to spend $5 billion (not a typo, billion with a ‘b’) on original content next year, and they keep unveiling one big project after another. Here’s the latest: A Netflix Original Film from Christopher Guest, the director of classic mockumentaries (although he hates that term, never use it in front of him for any reason, and I say this from experience) like Waiting For Guffman and Best in Show, and one-third of the mock-rock band Spinal Tap, whose own faux documentary essentially invented the entire genre of fake-doc comedies.

Guest’s Netflix film (his first feature since 2006’s For Our Consideration) is called Mascots; here’s the official synopsis from today’s announcement:

Welcome to all the drama, intrigue, and occasional excitement of The 8th World Mascot Association Championships, where a group of “unusual” men and women, with big heads and furry suits, compete to win the prestigious Gold Fluffy Award and be crowned the best mascot in the world.

It doesn’t say Mascots will be a fake documentary a la Guffman or Spinal Tap, but with that premise, it’s hard to imagine it won’t be; it’s basically the exact same story as Best in Show shifted from a dog show to a mascot competition. No word yet on which of Guest’s beloved repertory company of improv comedy actors (like Eugene Levy, Catherine O’Hara, Michael McKean, Parker Posey, and Jennifer Coolidge) will join the film. But with Mascots due on Netflix in 2016, it’s only a matter of months until we know. Whoever’s in it, it’s another big coup for Netflix. What’s next?
