Emma Corrin, the queer non-binary actor who starred as Princess Diana in “The Crown,” is heading to FX/Hulu to solve “A Murder at the End of the World.” The team behind cult series “The OA,” Brit Marling and Zal Batmanglij, created this limited mystery series, and Corrin stars as a young amateur detective (a profession currently trending hard in the media thanks to the success of “Only Murders in the Building” and “Poker Face”) who has to catch a killer on the loose at a remote retreat before the murderer strikes again. Rounding out the cast are some familiar faces/suspects: Clive Owen, “Twin Peaks” alum Joan Chen, “Triangle of Sadness” co-star Harris Dickinson, young gay playwright Ryan J. Haddad and queer Tony Award nominee Raul Esparza. The episodes arrive on Hulu during sweater weather — Nov. 14, specifically — which technically makes it a cozy mystery.
