1. Psycho (1960) Paramount Pictures Directed by: Alfred HitchcockWritten by: Joseph StefanoTo be fair, Psycho, which is largely regarded as one of the greatest horror films, wasn't completely snubbed at the Oscars — Hitchcock picked up a Best Director nomination, and Janet Leigh was nominated for Best Supporting Actress. But what about Anthony Perkins' pitch-perfect performance as Norman Bates? Or the movie as a whole? 2. The Birds (1963) Universal Pictures Directed by: Alfred HitchcockWritten by: Evan HunterCuriously enough, The Birds earned an Academy Award nomination for Best Special Effects, even though the titular birds are probably the least convincing thing about the movie. It's still a quality horror film, with Hitchcock's expert direction elevating an otherwise silly concept to greatness. 3. Rosemary's Baby (1968) Paramount Pictures Directed by: Roman PolanskiWritten by: Roman PolanskiIf Rosemary's Baby was good enough to earn a nomination for Best Adapted Screenplay, why not a nomination for Best Picture? The film remains one of the most powerful and unsettling horror films ever made, and Mia Farrow is brilliant in the titular role of Rosemary, a woman manipulated by everyone around her. 4. Night of the Living Dead (1968) Elite Entertainment Directed by: George A. RomeroWritten by: George A. Romero and John A. RussoIn addition to being regarded as the single biggest inspiration to current zombie entertainment, Night of the Living Dead is also a brilliant allegory for civil rights. (Yes, really.) It's smarter than anyone gave it credit for when it was released, which is too bad: The gore distracted from its awards season potential. 5. Don't Look Now (1973) British Lion Films Directed by: Nicolas RoegWritten by: Allan Scott and Chris BryantBased on a short story by Daphne du Maurier, Don't Look Now is a strange, somber horror film with a gut punch of an ending. The movie earns its shocking climax with gorgeous direction by Roeg and strong performances from leads Donald Sutherland and Julie Christie, but it didn't earn any Oscar nominations. 6. Carrie (1976) United Artists Directed by: Brian De PalmaWritten by: Lawrence D. CohenCarrie wasn't completely snubbed at the Academy Awards: Sissy Spacek and Piper Laurie both earned nominations, for Best Actress and Best Supporting Actress, respectively. Still, it's worth considering the entire film, which is so much more than its climactic (and bloody) prom revenge sequence. 7. The Omen (1976) 20th Century Fox Directed by: Richard DonnerWritten by: David SeltzerWhile The Omen won an Academy Award for Best Original Score and earned another nomination for Best Original Song, it was mostly overlooked. But the film is a smart, scary supernatural thriller that also incorporates elements of psychological terror, much like Rosemary's Baby. 8. Suspiria (1977) Anchor Bay Directed by: Dario ArgentoWritten by: Dario Argento and Daria NicolodiRealistically, Suspiria is just too weird to ever be an Oscars contender. But such a singular and mesmerizing vision is worthy of commendation. Argento's horror film elevates the Italian giallo to something more artful, which is why Suspiria remains such an enduring influence in horror. 9. Halloween (1978) Anchor Bay Directed by: John CarpenterWritten by: John Carpenter and Debra HillOK, Halloween isn't exactly an Oscars movie, but it's such a stunning achievement that it certainly deserved more recognition than it got. It established the slasher genre — it's tense and brilliantly executed. And an Academy Award nomination could have changed the way we look at horror films. 10. Alien (1979) 20th Century Fox Directed by: Ridley ScottWritten by: Dan O'BannonAlien's visual effects are great, and it deservedly won that Academy Award. But the film is such an achievement beyond that. While the entire franchise has merit, the first film is notable for being a more contained story — a sort of haunted house in space. And Sigourney Weaver was instantly iconic as Ripley. 11. The Shining (1980) Warner Bros. Directed by: Stanley KubrickWritten by: Stanley Kubrick and Diane JohnsonStephen King may not have been pleased with Kubrick's adaptation of The Shining, but as a stand-alone work, the film is incredible. It could easily have been a Best Picture contender — even with Kubrick and star Shelley Duvall nominated for Razzie Awards for Worst Director and Worst Actress, respectively. 12. Poltergeist (1982) MGM Directed by: Tobe HooperWritten by: Steven Spielberg, Michael Grais, and Mark VictorThere's a lot going on in Poltergeist, which takes a simple haunting story and adds a whole bunch of supernatural weirdness. But as odd as it is, it's also very effective and often warm and funny. And really, what more could you ask for in a Best Picture nominee? 13. A Nightmare on Elm Street (1984) New Line Cinema Directed by: Wes CravenWritten by: Wes CravenPerhaps the most unconventional choice on this list, A Nightmare on Elm Street is classic horror for a reason. The original film is subtler than the increasingly over-the-top sequels, but it still offers a nice blend of traditional horror with the surrealist elements of nightmares. 14. Henry: Portrait of a Serial Killer (1986) Dark Sky Films Directed by: John McNaughtonWritten by: John McNaughton and Richard FireMost horror films that are as brutal and hard to watch as Henry: Portrait of a Serial Killer don't get much critical claim, but Henry was widely praised at the time by top critics. Michael Rooker in particular is Oscar-worthy as the titular serial killer, delivering an intense and unnerving performance. But he didn't get his due from the Academy. 15. The Fly (1986) 20th Century Fox Directed by: David CronenbergWritten by: David Cronenberg and Charles Edward PogueJeff Goldlbum is both creepy and sympathetic as Seth Brundle, slowly devolving into a terrifying human-fly hybrid. Despite the grossness of the film — it is, after all, filled with Cronenberg's trademark body horror moments — The Fly is a fascinating and ultimately poignant look at science gone wrong. 16. 28 Days Later (2002) Fox Searchlight Pictures Directed by: Danny BoyleWritten by: Alex GarlandLike Night of the Living Dead, 28 Days Later used zombies to make a larger point about humanity. Beyond that, it's bleak and surprisingly terrifying — the best socially conscious genre films don't let the message detract from the horror, and they deserve recognition for doing so.
