With Hallowe’en around the bend, we asked a coven of actors and filmmakers—and the Letterboxd crew—about their favorite horror movie performances… and now it’s your turn. A catch: to ensure we don’t (understandably) end up with lists full of Carries, Jennifers and Pearls, we’re channeling the love into celebrating the craft of ing roles in scary movies. We all obviously adore Sigourney Weaver as Ripley, but what about Ian Holm as her frenemy Ash? For this Showdown, list your ten favorite non-lead horror performances and don’t forget to mention the actor/​character in the notes for each film. This is your chance to highlight the shining sidekicks, the sinister villains, the funny games or the comic relief… they all float down here.
