Patrick J. Adams and Jason Isaacs have signed on to star in NBC's Rosemary's Baby. We reported earlier this month that Zoe Saldana will star as the title character, Rosemary Woodhouse.

The story centers on Rosemary and Guy Woodhouse (Patrick J. Adams), a young married couple who move into a Paris apartment that has a haunted past. When Rosemary becomes pregnant, she begins to suspect that her husband and new neighbors have sinister plans for when the child is born. Jason Isaacs is playing warlock/coven leader Roman Castavet, a role originally played by Sidney Blackmer in director Roman Polanski's feature film adaptation of Ira Levin's horror novel, which starred Mia Farrow and John Cassavetes as Rosemary and Guy.

Agnieszka Holland is directing the four-hour mini-series, from a script provided by Scott Abbott (Introducing Dorothy Dandridge, Winchell) and James Wong (American Horror Story). Production is scheduled to begin later this month in Paris, with Joshua D. Maurer, Alixandre Witlin and David Stern serving as executive producers.

Patrick J. Adams currently stars on the hit USA Network series Suits, which is under the NBCUniversal family of networks. Jason Isaacs previously starred in the short-lived NBC series Awake.
