New Doctor Who star Peter Capaldi has admitted to first-day nerves after stepping on to the show's set.
The actor, who has replaced Matt Smith as the TV Time Lord, joined co-star Jenna Coleman in Cardiff.
He said: "New job, first day, slightly nervous. Just like the Doctor, I'm emerging from the Tardis into a whole other world."
Viewers got their first glimpse of Peter at the end of the Christmas Day episode of the long-running science fiction show.
Show supremo Steven Moffat said: "First the eyebrows! Then, at Christmas, the face! Coming soon, the whole Doctor. In the Cardiff studios, the Capaldi era begins."
Filming on the eighth series of the show will go on until August with director Ben Wheatley coming on board.
Figures released by the BBC show that Doctor Who was the most viewed programme on the iPlayer over the festive period, with almost two million requests to view the Christmas Day edition.

The new data shows that there 102 million views in total on the iPlayer during the 12-day period from December 21, and January 1 was the busiest day ever with 11 million requests.
