Quartet star Sheridan Smith has been cast as Alfie singer Cilla Black in a new TV mini-series. The actress will play British singer-turned-TV star Black in director Jeff Pope's new drama, which will chronicle the entertainment industry veteran's early career and her links to the Beatles. Black was a friend of Ringo Starr when he replaced Pete Best in the band and urged manager Brian Epstein to sign the young talent. She celebrated 50 years in showbusiness in 2013. Sheridan says, "Her life story is fascinating. I'm so excited and can't wait to start filming."
