Who Killed Santa? A Murderville Murder Mystery (2022)
Murderville is essentially a blend of a cop show parody, a gameshow, and an improv performance. The setup involves a scripted murder mystery in which a celebrity guest, playing the character assigned to solve the crime, is NOT shown the script or provided any sort of preparation. This guest host then needs to stumble through the story while the rest of the cast improvs around them. The show typically uses only one guest, but this isn't a normal episode. For the Christmas special, we get two or three, depending on whether you count a brief surprise spot from Pete Davidson as a real guest. Jason Bateman is around from the start, with Maya Rudolph added about halfway through. Guiding the guest star(s) is Will Arnett, playing Detective Terry Seattle, a parody of the typical hard-as-nails lead. Seattle has an ongoing subplot involving his ex-wife, who's also his boss, though this is less of a factor in this episode. Seattle gets a few scenes with side adventures in this episode. Arn
