Apartment 7A, a prequel to the 1968 psychological horror movie Rosemary’s Baby, has a pre-Halloween release date, exclusively on Paramount+. The Julia Garner-led flick will drop Friday, Sept. 27. Rosemary’s Baby, written and directed by Roman Polanski, starred Mia Farrow as Rosemary Woodhouse, a young newlywed who suspects her New York apartment building neighbors belong to a cult, and then fears that the baby she winds up carrying is the son of Satan. Apartment 7A, starring Garner (Ozark) and directed by Natalie Erika James (Relic), is set in New York City circa 1965 and explores what happened in that apartment before Rosemary moved in.
