Jenna Coleman has revealed the new series of Doctor Who could “scare” youngsters with a darker theme.

Actress Jenna, who plays Doctor Who's sidekick Clara Oswald, will continue in her role alongside new Time Lord Peter Capaldi.

She said: “I saw the first episode and it’s amazing how different it feels. It’s darker.

"The limits feel like they’re being pushed more in terms of the danger and the dread. It’s scarier, that’s for sure.”

On returning with a new Timelord, she said: “Steven said to me it’s like seeing your friend after a major operation and you kind of have to start all over again.

“It’s like a death without a death. The whole dynamic’s been thrown up in the air. What she soon realises is this Doctor doesn’t really know who he is either.

"He’s an adrenalin junkie and his curiosity takes him to new levels of danger.”

Speaking in Empire magazine, 56-year-old Capaldi admits he was beyond thrilled to land the role.

He said: “I thought, ‘I wonder who they’re going to get?’ And then suddenly it was me. When he got the first call from his agent, I laughed very hard, joyfully.

"It was such a wonderful notion.”

The new eighth series starts on BBC1 with a feature length episode on August 23, called Deep Breath.

The beginning of the Twelfth Doctor’s era sees the return of fan favourites The Paternoster Gang - Madame Vastra (Neve McIntosh), Jenny Flint (Catrin Stewart) and Strax (Dan Starkey) – in a pulse-racing adventure through Victorian London.

It will be promoted with a world tour by Capaldi and Jenna, which kicks off in Cardiff next week.
