As the first full day of filming got under way Tuesday on the eighth season of Doctor Who, the BBC released the first official image of new Doctor Peter Capaldi on the Cardiff set with co-star Jenna Coleman.

“New job, first day, slightly nervous," Capaldi said in a statement. "Just like the Doctor, I'm emerging from the TARDIS into a whole other world.”

Announced in August as the Twelfth Doctor, Capaldi was glimpsed in the 50th-anniversary special "The Day of the Doctor" before making his official debut in the Christmas episode "The Time of the Doctor."

“First the eyebrows! Then, at Christmas, the face! Coming soon, the whole Doctor," Executive Producer Steven Moffat said. "In the Cardiff studios, the Capaldi era begins.”

The Season 8 premiere is written by Moffat, with the second episode penned by Phil Ford.
