The Starz network is gearing up the fourth, American-centric season of “Torchwood” for a July 2011 launch, but until then, they’ve released a quickie teaser trailer and poster for the upcoming season.

The plot? Everyone on the planet has suddenly become immortal, and the Torchwood team led by Captain Jack (John Barrowman) and Gwen (Eve Myles), and featuring new castmembers Mekhi Phfifer and Alexa Havins, must discover why. Bill Pullman also joins the show as its lead villain.
