One day, you could find yourself debating whether Torchwood season ten was as good as season nine, if current plans continue. At least, star John Barrowman says the current plan is for seven more years of the Doctor Who spinoff.
Talking to a newspaper about the new U.S.-U.K. co-production, Torchwood: The New World, Barrowman said:
I have turned down a load of other shows to make Torchwood. We'll be filming it in LA as it's now a collaboration between the BBC and the Starz Network in America. They're planning to make it for the next seven years. So I'll be spending six months a year in Hollywood and six back in the UK.http://io9.com/5716614/barrowman-torchwood-could-run-another-seven-years
