Steven Moffat has revealed that the next series of Doctor Who will see some major changes.
The hit show's writer suggested that the casting of Peter Capaldi as the 12th incarnation of the Time Lord has brought about much-needed tweaks, as he spoke at Hay Festival, reported Metro.
"We haven't made much of a change to Doctor Who since it came back in 2005. It's been the same show. It's maybe amped some things up and lowered some other things, but it's basically the same," he said.
"I just felt it needs to be a bit more different now. It needs to be surprising again!" he added.
Steven said casting a 'handsome, yet quirky, young man with entertaining hair' would have resulted in Doctor Who becoming too formulaic.
"It would have just exposed the formula. We'd have found somebody great and people would have liked him, but the show would have just become that little bit more ordinary," he continued.
Peter replaced Matt Smith as the Doctor in the final scene of last year's Christmas special.
The 56-year-old will be joined by companion Jenna Coleman in Doctor Who's new series, which is expected to begin in August.
