Cherry Jones has joined the cast of the upcoming Apple drama series “Five Days at Memorial,” Variety has learned.

The series is based on the Sheri Fink novel of the same name. It chronicles the first five days in a New Orleans, LA, hospital after Hurricane Katrina made landfall. When the floodwaters rose, the power failed, and the heat climbed, exhausted caregivers were forced to make life-and-death decisions that haunted them for years to come.

Jones will play Susan Mulderick, a hospital nursing director and head of the emergency preparedness committee, who becomes the designated incident commander for Hurricane Katrina. Jones joins previously announced cast members Vera Farmiga, Adepero Oduye, Julie Ann Emery, and Cornelius Smith Jr.

Jones is a three-time Emmy Award winner — the first for the Fox series “24,” the second for Hulu’s “The Handmaid’s Tale,” and most recently for HBO’s “Succession.” She also recently appeared in the Apple limited series “Defending Jacob” opposite Chris Evans, Michelle Dockery, and Jaeden Martell. Her other TV roles include “11.22.63,” “American Crime,” and “Transparent.” On the film side, she has starred in features such as “Erin Brockovich,” “Cradle Will Rock,” and “The Village.” Jones is also an accomplished stage actress, having been nominated for five Tony Awards throughout her career.

She is repped by WME.

John Ridley and Carlton Cuse will co-write “Five Days at Memorial” in addition to serving as executive producers and co-showrunners. Fink will produce, with both Ridley and Cuse attached to direct as well. ABC Signature, where Ridley and Cuse are both under overall deals, will produce.
