STARZ! announced that Nana Visitor will guest star on their new series, Torchwood: Miracle Day. In addition to Torchwood alumni, John Barrowman, Eve Myles, and Kai Owen and new headliners, Mekhi Phifer, Bill Pullman and Alexa Havins, the 10-episode, hour-long series will also feature an impressive list of guest stars: Wayne Knight (“Seinfeld,” Jurassic Park), C. Thomas Howell (“Southland,” The Outsiders), Ernie Hudson (“OZ,” Ghostbusters), Nana Visitor (“Star Trek: Deep Space Nine”), John DeLancie (“Star Trek: The Next Generation”), Mare Winningham (Mildred Pierce, George Wallace) and Frances Fisher (Titanic, The Lincoln Lawyer).

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.

Torchwood: Miracle Day premieres July 8 on STARZ!
