Warning: Contains minor SPOILERS for Midnight Mass.

Netflix's long-awaited horror series Midnight Mass is officially available now — here's a breakdown of the cast and characters both new and familiar. Created by popular horror maestro Mike Flanagan, Midnight Mass is billed as his most personal project to date. The series also continues Mike Flanagan's successful partnership with Netflix. Midnight Mass is already a proven hit with critics, earning rave reviews and a 95% rating at Rotten Tomatoes. Equally, it's been praised by Stephen King and countless fans who received early screenings.

Midnight Mass is set on the isolated fishing town of Crockett Island (a.k.a. the Crock-Pot). With a population of only 127 people, the small community continues to reel from years of unfortunate events that affected their way of life. Fate appears to smile upon them, however, when a former resident returns and a new priest arrives to fill in for their aging Monsignor. Eager to rejuvenate the town and its residents, Father Paul stirs up a religious fervor with a series of seemingly miraculous events that increasingly engulf and divide the island.

Though following the popular The Haunting of Hill House and its separate but thematically similar follow-up, The Haunting of Bly Manor, the highly-anticipated story of Midnight Mass greatly precedes them both. In fact, it's long been a passion project of Mike Flanagan's. And in order to finally bring his vision to life, he amassed a sprawling cast of recognizable faces from both those aforementioned shows and other works. Rounding things out with some relative newcomers, Midnight Mass delivers a talented ensemble that will stay with viewers long after their binge-watch.
