Meg Ryan has signed on to produce and star in the HBO miniseries, The Best Awful.

It's an adaptation of the Carrie Fisher novel that recounts the further adventures of the heroine from Fisher's best-selling, thinly veiled autobiographical novel, Postcards From the Edge. She was a bipolar, ex-actress, celebrity talk show host with a 6-year-old daughter, a gay ex-husband, an aging movie star mother and an unshakable will to survive, says The Hollywood Reporter. Her post-divorce trauma leads her back to the use of prescription drugs, a wild trip to Mexico with her tattoo artist and, ultimately, a rehab clinic.

No word on a production schedule for The Best Awful.
