Luther” and “Crossbones” creator Neil Cross is to revive 1970s sci-fi series “Sapphire & Steel,” which starred Joanna Lumley and David McCallum as time-traveling special agents protecting the universe from evil.

“I’m planning to — it looks like I’m going to — relaunch ‘Sapphire & Steel,'” Cross told the Nerdist Writers’ Panel podcast. He added that it was “a late ’70s science fiction horror show, which had incredibly low budgets, so every single episode was a bottle episode where the enemy is time itself. So it would tell ghost stories and monster stories but in every episode somehow time was the villain.” Cross, who has also written for “MI-5” and “Doctor Who,” described the lead characters as “proto Mulder and Scully.”

“There’s a broadcaster in the U.K. that’s very, very keen to do it,” he claimed.

Cross added that he is working with director Darren Aronofsky on HBO paranormal series “Riverview,” which centers on a family who move into a haunted apartment in New York.

He also spoke about the difficulty of casting the lead for the Fox remake of “Luther,” the sequel to the Guillermo Del Toro-produced and Jessica Chastain-starring horror film “Mama,” and the revival of Sam Raimi’s feature film remake of “The Day of the Triffids,” on which Mark Gordon is a producing partner.
