Danny Horn – who will be appearing in Doctor Who this Christmas - has spoken to The Telegraph & Argus about his role in the special.

He told them: ”It’s been like a bizarre dream. I finished the Central School of Speech and Drama on the Friday, had the audition on the Monday and by Thursday I was filming in Cardiff. I was very excited about the audition but didn’t think I’d get it. It took a month to film and I’ve been up and down to Cardiff. It’s a relatively good part.”

The actor revealed that his character spends most of the story with singer Katherine Jenkins, who will be making her acting debut in the episode. “We were together for a lot of the episode,” he said. ”Let’s just say I might be a bit of a hero with the boys.”

He finished: “Working with Michael was fantastic as he’s one of my heroes, and Matt is brilliant to work with - absolutely fantastic.” The special is due to air on Christmas Day.
