Sept. 9 (UPI) -- Chernobyl actress Emily Watson has joined the cast of a new ITV psychological thriller.
Variety confirmed the 52-year-old British actress will star in a miniseries adaptation of the novel Too Close.
Too Close is written by actress and author Clara Salaman, who penned the book under the pseudonym Natalie Daniels. The adaptation hails from Snowed-In Productions and All3Media International.
Watson plays Dr. Emma Robinson, a forensic psychiatrist assigned to work with Connie, a woman accused of a heinous crime, who claims to not remember a thing. A psychological game ensues as Emma attempts to uncover the truth about the incident.
Deadline said Ruth Kenley-Letts will executive produce the miniseries, with All3Media to handle global sales.
"Working with Clara Salaman on this adaptation of her novel has been a joy. She is a bright new talent to screenwriting and it is a testament to her writing that Emily Watson, one of our finest and most accomplished actors, has signed up to play the part of Emma," Kenley-Letts said.
ITV head of drama Polly Hill, who commissioned the series, said she's "delighted" Watson signed on to the project.
"Too Close is a brilliant script where you are never sure who has the power -- the psychologist or her patient, or whether Connie is the monster she's portrayed as," Hill added.
Watson played Ulana Khomyuk on Chernobyl, which aired on HBO in the spring. She is also known for the films Breaking the Waves, Hilary and Jackie and The Theory of Everything.
