Matt Smith discusses the return of Doctor Who. Now in its 50th year, Doctor Who will return to BBC One with eight epic adventures - from a modern day urban thriller, to a ghost story, to an underwater siege. The new series will have plenty of surprise guest stars and will also introduce new monsters, as well as bringing back fan favourites, the Ice Warriors and Cybermen. Moderated by Boyd Hilton at the Apple Store, Regent Street in London.
