9’Rosemary’s Baby' (1968)

Directed by Roman Polanski

Rosemary’s Babyfollows married couple Rosemary (Mia Farrow) and Guy (John Cassavetes), a stage actor, as they move into a new apartment in New York. The couple quickly befriends their neighbors, the Castevets. Eventually, Rosemary becomes pregnant, but her pregnancy is filled with unexplained symptoms and immense pain. Strangely, her husband’s acting career starts flourishing out of the blue, and he becomes more distant. As her pregnancy progresses, Rosemary starts to suspect that her husband and neighbors are scheming against her and her unborn baby.

Rosemary’s Babymarked a shift in the horror genre, as it forwent all the classic monstrous creatures and jump scares, and focused on the psychological horror of Rosemary’s situation. Satan is a major component of Rosemary’s Baby, but most of the horror stems from Rosemary’s isolation and loss of trust in everybody around her. As her pregnancy progresses, Rosemary gradually realizes the sinister plan conducted by her husband and neighbors and her mental health unravels. Most importantly, Rosemary’s Baby brought horror movies to the city when the standard was remote or gothic settings. Rosemary’s Baby explored themes of motherhood and bodily autonomy. It is impossible to watchmodern horror movies discussing social issueswithout seeing its influence on the genre.

While the horror genre is one of the most popular genres now, in the mid-2000s it was struggling and losing the interest of the public due to the unoriginality of movies. WhenSawwas released, it reignited interest in the genre due to its new concept and ideas.Sawintroduced theconcept of survival gamesthat tested its subjects' physically and mentally to horror.Sawalso changed how franchises are made, as theSawfranchise has a central narrative revolving around who Jigsaw is and his motives, rather than multiple movies that have minimal connections. TheSawfranchise originally had yearly releases, a model that inspired all franchises, including theMarvel Cinematic Universe.

5’Frankenstein' (1931)

Directed by James Whale

Henry succeeds in creating life by using electricity on the created body. However, he doesn’t know that the brain he used is a damaged one. Frankenstein’s Monster (Boris Karloff) is childish and innocent, but he is rejected from society and by his creator for his grotesque and monstrous nature.

Frankenstein’s Monster has become a symbol of the horror genre, with many adaptations ofMary Shelley’s 1818 novelstill being produced to this very day. The 1931Frankensteinwas the first full length feature adaptation of Shelley’s novel and introduced the visual depiction of the monster to the general public and pop culture.Frankensteincreated the early template of creature features, especially those sympathizing with the creatures, and introducedthe mad scientist archetype.

Frankenstein

Directed by George A. Romero

Night of the Living Deadstarts with siblings Barbra (Judith O’Dea) and Johnny (Russell Streiner) visiting a cemetery to visit their father’s gift. The siblings are suddenly attacked by a pale man and Johnny is killed. Barbara flees to a nearby farmhouse for safety. In the farmhouse, she meets Ben (Duane Jones) who assumes leadership and barricades all the windows and doors. Barbara also finds other people taking shelter in the farmhouse, including Harry (Karl Hardman), his wife Helen (Marilyn Eastman), and their young daughter Karen (Kyra Schon), who has been bitten, as well as a young couple, Tom (Keith Wayne) and Judy (Judith Ridley). Things get more complicated as the house is surrounded by zombies and the survivors have to find a way out.

Despite never using the word “zombie” to refer to the monsters,Night of the Living Deadcreated the blueprint forthe modern zombie. The idea that a zombie is a reanimated, slow, dimwitted, and flesh-eating corpse, killed by having its head destroyed originates fromNight of the Living Dead.The movie is also credited with pioneeringthe splatter genre. While the movie does not include as much extreme violence as many modern splatter movies, it was a pretty violent movie for its time. The casting of Jones as Ben was groundbreaking, as it was uncommon at the time in Hollywood to cast a black man as the main protagonist and hero,inadvertently extending the movie’s social commentary to race.

This killer archetype is replicated in various slasher movies, includingFriday the 13thandA Nightmare on Elm Street.
