In a power pairing, The New Adventures Of Old Christine creator Kari Lizer has teamed with The Closer star Kyra Sedgwick for a half-hour single-camera Kari Lizercomedy project set up at HBO. Sedgwick is set to star and Lizer will write the untitled comedy, which the two will executive produce for Warner Bros. TV and Lizer’s studio-based Kari’s Logo Here banner.

It centers on Kate (Sedgwick) who was a nun in the order of the Sisters of Mercy, San Mateo Chapter, but disillusioned by a lifetime of service to the church and a marriage she no longer believes in, she has walked out on everything she’s known since the age of 17. 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.

Sedgwick’s seven-season run on TNT’s drama The Closer, which featured comedic elements, earned her an Emmy Award. When Lizer previously teamed with an Emmy-winning actress for a comedy starring vehicle, Julia Louis-Dreyfus on Old Christine, the collaboration landed Louis-Dreyfus another Emmy.

Four years ago, HBO developed a comedy from Simpsons writer-producer Tim Long, which had Molly Shannon attached to star as a nun re-adjusting to society after leaving the convent.

Best known for her dramatic roles, Sedgwick most recently did an arc on Fox’s single-camera cop comedy Brooklyn Nine-Nine. She executive produces TNT’s upcoming supernatural medical drama Proof and will next be seen in the feature Time Out Of Mind. She is repped by CAA and Impression Entertainment. Lizer is with Vision Art’s Scott Schwartz.
