New York City dancer Terry Gionoffrio sustains a serious ankle injury mid-performance in a Broadway production.

She follows Broadway producer Alan Marchand home to the Bramford apartment building and becomes sick from her anti-pain medication.

She is befriended by elderly Bramford residents Minnie and Roman Castevet, who offer her an apartment rent-free.

Terry discovers a secret passageway into Lily's apartment and finds a grimoire containing images of her talisman and a chained woman giving birth to a demon.

A nun reveals that Joan had been subjected to "ungodly things", and was being chased when she ran into an oncoming bus, killing her.

[a] In addition, Amy Leeson and Scott Hume appear as married couple Rosemary and Guy Woodhouse, respectively.

[f] In 2008, a remake of Rosemary's Baby (1968) was in development from producers Michael Bay, Andrew Form, and Brad Fuller.

[11][12] In March 2021, it was reported Natalie Erika James would direct the psychological thriller film Apartment 7A.

Following the success of the A Quiet Place franchise, the project was among several scripts that the studio was developing with a similar tone.

[4] By the time filming had ended, additional casting announcements included Marli Siu,[7] Rosy McEwen,[9] Jim Sturgess, Kevin McNally, Andrew Buchan and Kobna Holdbrook-Smith.

[16][17] In August, the Writers Guild of America determined the film's final writing credits and confirmed it to be based on Levin's novel.

The website's consensus reads: "Apartment 7A is slickly assembled and solidly acted, but the lingering memory of Rosemary's Baby and a predictable prequel template make for a sub(par)lease.

[25] Writing for IGN Movies, Katie Rife noted that "although the film’s themes and horror are rote, creative choreography and strong performances from the core cast make it an entertaining watch".
