The Apartment 7A Trailer Really Doesn't Want You To Know It's A Rosemary's Baby Prequel

Back in 2021, it was announced that "Relic" director Natalie Erika James was teaming up with John Krasinski for the new horror film "Apartment 7A." At the time, the movie was described as a "psychological thriller," but little else was known about the project. Then, in 2022, a bombshell. A theory provided by Bloody Disgusting suggested "Apartment 7A" is actually a secret prequel to "Rosemary's Baby," which has since been confirmed by additional reports (including, most recently, Vanity Fair's first look at the film). The horror movie is now officially set to premiere on Paramount+ 56 years after Roman Polanski's celebrated 1968 film adaptation of the 1967 novel originally bowed in theaters.

Breakout "Ozark" star and future "Fantastic Four" actor Julia Garner is starring in the film as Terry Gionoffrio, the woman who (er, spoiler for a 56 year old movie coming up) dies at the start of "Rosemary's Baby" — though up until very recently, that wasn't a sure thing. Co-written by Natalie Erika James, Christian White, and Skylar James, "Apartment 7A" also stars Dianne Wiest as Minnie Castevet, the devil-worshipping neighbor portrayed by Ruth Gordon (in an Oscar-winning performance) in Polanski's film.

Now, we finally have the first footage from "Apartment 7A" courtesy of today's trailer premiere. You can check it out above.

Julia Garner's Terry Gionoffrio doesn't seem to be having the best luck when the trailer begins, severely injuring her ankle during a dance performance. Of course, given what happens at the start of "Rosemary's Baby," we know that bad luck is going to continue — but not until we learn the precise details of the poor girl's suffering. Those details are recounted in what looks to be truly horrifying detail in "Apartment 7A," with the trailer showing Gionoffrio moving into a new apartment building called the Bramford and seemingly getting her post-injury life back on-track. Unfortunately, her new building is also home to a couple (played by Dianne Wiest and Kevin McNally), who have not only have nefarious intentions, but represent an evil force that inhabits the Bramford.

Much like Mia Farrow and John Cassavetes' characters in "Rosemary's Baby," Gionoffrio is soon tormented by her sinister neighbors, who, as a nun warns the young dancer in the trailer, did "ungodly things" to the previous tenant. The official synopsis that arrived with the new trailer reveals more details:

"After an evening she can't fully remember, disturbing circumstances soon have [Gionoffrio] second-guessing the sacrifices she's willing to make for her career as she realizes that something evil is living not only in Apartment 7A, but in the Bramford itself."

As confirmed earlier this year, "Apartment 7A" is set to hit the Paramount+ streaming service on Sept. 27.
