Sapphire & Steel is a British television science-fiction fantasy series starring David McCallum as Steel and Joanna Lumley as Sapphire. Produced by ATV, it ran from 1979 to 1982 on the ITV network. The series was created by Peter J. Hammond who conceived the programme under the working title The Time Menders, after a stay in an allegedly haunted castle. Hammond also wrote all the stories except for the fifth, which was co-written by Don Houghton and Anthony Read.
On 8 July 2015, Neil Cross announced that he was writing a follow-up to the show. In the press release, Cross stated that a British broadcaster was ‘extremely keen’ to finance the reboot. The writer went on to describe the follow-up as “where the enemy is time itself. There’s ghost stories and monster stories and time is the villain.” Cross describes the new series as a ‘Science Fiction/Horror’ mix rather than the traditional 1970s Sapphire & Steel, which was defined as ‘Science Fiction/Fantasy’.
