Best Halloween movies to watch: 31 days of horror this October

If there’s one thing we love here at Polygon, it’s the Halloween season.

We cover horror year-round, whether it’s the best horror movies you can stream at home or the best horror movies on Netflix, and generally, we have our finger on the undead pulse of the newest and ghastliest releases in horror. We even have a list of the best horror movies of the year (ranked by scariness, of course).

Even still, Halloween is an especially spooky time of year, and it warrants special attention and celebration.

For the past three years, Polygon has put together a Halloween countdown calendar, selecting 31 of our staff’s top horror-themed or Halloween-adjacent picks across movies and TV throughout the month of October, all available to watch at home. We’ve loved doing it, so much so that we’re bringing it back again — this time with a whole new batch of films and shows to choose from.

Every day for the month of October, we’ll add a new recommendation to this countdown and tell you where you can watch it. So curl up on the couch, dim the lights, and grab some popcorn for a terrifying and entertaining marathon of horrific delights.

Oct. 1: Messiah of Evil

A undersung classic of ’70s cosmic horror, Willard Huyck and Gloria Katz’s Messiah of Evil is a surreal and nightmarish experience that more than deserves its status as a cult horror classic.

The film centers on Arletty, a young woman who journeys to the remote coastal town of Point Dume, California, to track down her missing father, a reclusive painter who is plagued by disturbing visions of an impending apocalypse. After crossing paths with an eccentric aristocrat and his groupie companions, the group bears witness to the realization of the painter’s prophecy, as the townspeople are transformed into flesh-eating ghouls and the messiah of evil makes his return to the mortal realm.

At times convoluted and bizarre, Messiah of Evil is a genuinely entertaining horror thriller filled with memorable scares and chilling set-pieces. From a cross-eyed albino man gleefully devouring a field mouse whole to a unsuspecting woman watching a Western as the theater around her slowly fills with ravenous undead zombies, it’s a dreamy and frightening experience that lands somewhere between the ineffable gothic horror of H.P. Lovecraft and the anti-consumerist allegories of George A. Romero. The horrors hold up over 50 years after it was first released, and with just the right combination of inadvertent silliness and legitimate terror, Messiah of Evil is a satisfying watch and an excellent start to a month of horrors. —Toussaint Egan
