Laura Linney‘s cancer patient Cathy is getting a new friend on Showtime’s “The Big C.”
Susan Sarandon has booked a multi-episode arc as Joy, a cancer survivor who befriends Cathy, according to The Hollywood Reporter.
“She’s another cancer survivor who has used her cancer experience in a unique way trying to inspire other people,” creator Darlene Hunt tells THR. “She makes Cathy question whether she’s doing enough with her own cancer experience.”
Sarandon played a woman suffering from cancer in the movie “Stepmom,” so it won’t be her first time channeling a victim of the disease. She join’s Victor Garber as one of Season 3’s big guest stars. 
“The Big C” Season 3 premieres Sunday, April 8 on Showtime.
