Imagine a day when nobody dies. All across the world, nobody dies. And then the next day, and the next, and the next, people keep aging. They get hurt and sick but they never die. This is the extraordinary premise of the highly-anticipated Starz original drama series, Torchwood: Miracle Day, produced by BBC Worldwide Productions for Starz, BBC Cymru Wales and BBC Worldwide. The series will premiere on Starz July 8 at 10 pm ET/PT.

Today, the network announced that in addition to Torchwood alumni, John Barrowman, Eve Myles, and Kai Owen and new headliners, Mekhi Phifer, Bill Pullman and Alexa Havins, that the 10-episode, hour-long series will also feature an impressive list of guest stars: Alexa Havins (Seinfeld, Jurassic Park), C. Thomas Howell (Southland, The Outsiders), Ernie Hudson (Oz, Ghostbusters), Nana Visitor (Star Trek: Deep Space Nine), John de Lancie (Star Trek: The Next Generation), Mare Winningham (Mildred Pierce, George Wallace DVD) and Frances Fisher (Titanic, The Lincoln Lawyer).

Additional actors starring in the cult sensation include: Arlene Tur (Crash, Eat, Pray, Love) and Lauren Ambrose (Six Feet Under, The Other Woman) who join the cast in an extended guest role. The show's original creator, writer/producer Russell T. Davies, serves as executive producer along with BBC Worldwide Productions' SVP Julie Gardner, with Davies also serving as show-runner for Torchwood: Miracle Day.

Torchwood: Miracle Day begins with a day when nobody dies. The result: a population boom, overnight. With all the extra people, resources are finite. It's said that in four month's time, the human race will cease to be viable. But this can't be a natural occurrence - someone's got to be behind it. It's a race against time as C.I.A. agent Rex Matheson investigates a global conspiracy. The answers lie within an old, secret British institute. As Rex keeps asking "What is Torchwood?," he's drawn into a world of adventure, and a threat to change what it means to be human, forever.
