Starz CEO Chris Albrecht, before appearing before reporters at a TV critics tour, told Entertainment Weekly that “Torchwood is not one of the show we went into thinking about a yearly return.” Does that mean they aren’t happy with it? That’s not clear…and he appears to put it squarely on producer/creator Russell T. Davies shoulders. ““It’s about Russell T Davies … he has a lot of things on his plate. If Torchwood is at the top of his list, that will effect [sic] the future of Torchwood.”
But keep in mind – this is a British show that now has an American studio behind it. The BBC is still involved, and British TV productions don’t follow as rigid a production cycle. Starz could easily keep that concept, and produce Torchwood when desired.
