Netflix's Who Killed Santa? A Murderville Murder Mystery is here, and it looks like a bloody good time.

Based off the BBC3 series Murder in Successville, Murderville stars Will Arnett as Detective Terry Seattle, along with a slew of celeb guests who struggle to solve an increasingly silly murder mystery. While the first season of Murderville was comprised of six short but sweet episodes studded with stars like Conan O'Brien, Marshawn Lynch, and Kumail Nanjiani, Who Killed Santa? packs the laughs in at under an hour. And the biggest mystery of all might be the identity of a super-secret guest star whose identity is hidden in the trailer...

Buckle up for a master class in improv with some hilarious hijinks to match, even (or especially) if you're feeling like a real Grinch.
