Featured in the cast in the role of Millicent is five-time Emmy winner Harper ("Rhoda," "The Mary Tyler Moore Show"). She joins Sally Struthers of TV's "All in the Family," as Duchess Estonia Dulworth.

Harper, a lung cancer survivor, announced March 6, 2013, that she had been diagnosed with leptomeningeal carcinomatosis, a rare, terminal cancer. Given only three-to-six months to live, her diagnosis turned a corner, and neuro-oncologist Dr. Jeremy Rudnick said in September 2013 that the "Mary Tyler Moore" and "Rhoda" star "was pretty close to remission."

In April 2014, Harper said that although she is not "cancer-free," she remained optimistic and hopeful for the future. 

She recently told People, "I'm ready. I'm ready to go... Maybe that's the secret. That I'm absolutely – I don't want to, my God, I want to live to be 102.

"But I am not banking on anything, really, because we shouldn't. We don't know what's around the corner. I think you just take each day and get the best out of it and do what you can and have fun."

Harper also earned a 2010 Tony Award nomination for Looped.

Also planned for the rest of 2015: Million Dollar Quartet Aug. 19-Sept. 19; Saturday Night Fever with a newly revised book and musical arrangements, Sept. 23-Oct. 25; the Irving Berlin classic White Christmas for the holidays, Dec. 9-20 (at the Music Hall in Portsmouth, NH).
