Survivors, a remake of the 1970s TV series by Dalek and Blake's Seven creator Terry Nation, follows a group of Britons trying to build a new life for themselves after a virus has wiped out more that 99% of the world's population. The series, executive-produced by Primeval creator Adrian Hodges, has been an unexpected hit for the BBC, giving them almost a quarter of the viewing audience in its Tuesday evening timeslot, hence the speedy renewal.

The order for six more episodes also makes it more likely that American audiences will get a chance to see a show for themselves; keep watching the BBC America schedules for updates.
