One of your best sources for classic horror movies is free—-Kanopy. You can join through your library, just enter your library branch and your card number, and you get free movies, usually 6 a month. And Kanopy has wonderful classics for Halloween, like Nosferatu(1922), the silent original, or Phantom of the Opera(1925), again, a silent, with Lon Chaney(!), or Dr. Jekyll and Mr Hyde(1920), with John Barrymore(!). Or, if you want something a little more modern, Kanopy offers Invasion of the Body Snatchers(1956), the original starring Kevin McCarthy and Dana WinterDementia 13(1963), with Francis Ford Coppola‘s debut as director, or Don’t Look Now(1973), based on a Daphne du Maurier novel starring Donald Sutherland and Julie Christie(which won several BAFTA awards). Or maybe you want the epitome of horror(some would say) and the classic Night of the Living Dead(1968), the black & white original , or Day of the Dead(1985), the third in Romero’s series. Kanopy even has Two Evil Eyes(1990), with two stories, one directed by Romero, by Edgar Allen Poe. And, if you want 21st century, they offer Hereditary(2017), The Witch(2016) and What We Do in the Shadows(2014). You’re only problem is how to choose just six. Choose wisely and enjoy!
