An Emmy-winning actress has a new comedy project in the works for pay cable in which she will star as a nun. “The Closer” star Kyra Sedgwick is working with “The New Adventures of Old Christine” creator Kari Lizer on the project for HBO, in what Nellie Andreeva, writing on Deadline.com, calls “a power pairing.”

Sedgwick is slated to star, while Lizer will write the untitled comedy, with both executive producing. The project, from Warner Bros. TV and Lizer’s Kari’s Logo Here company, will feature Sedgwick as a nun named Kate who leaves the church after becoming disillusioned.

“No longer ‘Sister Katherine,’ she’s turned her back on her old life and now finds herself coming of age, trying to figure out who she is without her vows and what it means to be an ordinary woman. A person who believes in believing, she’ll try to figure out what or whom she’ll put her faith in now,” Andreeva writes.

While Sedgwick is best known for her roles on dramas, she recently appeared in Fox’s comedy “Brooklyn Nine-Nine.” She won a Primetime Emmy for outstanding lead actress in a drama series in 2010 for “The Closer,” following her fifth consecutive nomination for the role.
