The 57-year-old actor - who plays the titular Time Lord in the BBC sci-fi series - has confessed he and showrunner Moffat don't always see eye to eye when it comes to the "direction" of the show.

He said: "I think Steven's fantastic and the team we have are fantastic, and to be honest my hand are pretty full just playing the Doctor.

"I trust Steven completely. I have my ideas about where we should go and what the character should be like, and generally we always agree on those.

"Sometimes we don't, but it all comes out in the wash and I think it's good to have creative relationships when you can disagree with people."

Capaldi thinks the reason they sometimes disagree is because everyone has their own "very personal idea" of what 'Doctor Who' should be.

According to Digital Spy, he added: "I think everybody has their own idea of what Doctor Who is and it's not the same - everybody doesn't agree, and that's the way it should be.

"So I'm not interested in sticking my oar in where it's not necessary, but I will make my feelings felt if I feel it's going in the wrong direction."
