Doctor Who fans can expect a darker, more enigmatic version of the Time Lord, according to the latest incarnation of the science-fiction hero, Peter Capaldi.
The actor attended the screening of the first episode in Cardiff earlier, and met with thousands of fans.
He will be the 12th Doctor to grace our television screens when the series returns later this month, as Lizo Mzimba reports.
