Torchwood is a British science fiction drama television programme, created by Russell T Davies and starring John Barrowman and Eve Myles. It deals with the machinations and activities of the Cardiff branch of the fictional Torchwood Institute, who deal mainly with incidents involving extraterrestrials. An initial 13-part series was commissioned by the BBC as a spin-off from the 2005 revival of the long-running science fiction programme Doctor Who with which it is closely interlinked.
