Random (Leaked) Video: Doctor Who in Monmouth… and Cybermen!
The video features a pair of actors in and out of uniform as Cybermen, as well as some shots of David Tennant (The Tenth Doctor) rehearsing lines on the set and then filming (and re-filming) the corresponding scene with an unfamiliar partner. The video looks to be have been shot by an extra or bystander of some sort, as the video concludes with Tennant chatting up the people around the cameraman and signing autographs.
