Matt Smith, who plays the 11th Doctor has said that the return of UNIT in the next Doctor Who episode, The Power Of Three, is 'one for the fans' and he also praised Jemma Redgrave, who plays leader of UNIT, Kate Stewart.
He said: "I loved Jemma Redgrave! She was graceful, funny and charming and an absolute delight."
He added: "UNIT's return is one for the fans. I think they like cyclical things and we have a good story. It was great to do an episode with UNIT and I hope the true fans like it."
Executive producer of Doctor Who also promised that Chibnall's script will bring UNIT back, but with "a clever little twist".
"When I was a kid, and just getting obsessed about the Doctor (still not recovered) it was the Jon Pertwee era, and UNIT was as big a part of the show as the TARDIS itself," said Moffat.
"So when Chris asked if he could bring them back, I couldn't say yes fast enough. And being Chris, he gave it a clever little twist which I know the fans are going to love.
