The BBC has released a new promotional image and trailer for series eight of 'Doctor Who'. The new series sees Peter Capaldi step into the Tardis and take the role of the Doctor.
It's also announced the series will premier on Saturday, August 23.
Capaldi will be joined by Jenna Coleman as his assistant Clara, while a host of well-known stars will make guest appearances, including Frank Skinner, Ben Miller, and Keeley Hawes.
Here's the new trailer.
As you can see, it doesn't give much away. Clara is heard saying: "I don't think I know who the Doctor is anymore." Which could be a reference to Capaldi taking the character in a new direction.
Capaldi also asks: "Am I a good man?"
Capaldi will play the twelfth Doctor. When the announcement was made last summer, Capaldi admitted he was a life-long fan.
"I haven't really played 'Doctor Who' since I was nine," he said. To prepare for the audition, he read old Doctor Who scripts in front of the mirror.
So what can we expect from the new series? The first episode will be "exciting" and "disturbing", according to show writer Mark Gatiss.
"Peter has a very different energy to Matt Smith and to David Tennant," Gatiss told Digital Spy back in March. "He's older which changes everything – it's amazing what a change does!"
He added the new Doctor will have "a whole new set of rules."
