Who's Who for Time Lord Matt Smith
TV Time Lord Matt Smith has come face to face with a life-size replica of himself, in a real case of Who's who?
The Doctor Who actor met his double as he attended the launch of a new exhibition dedicated to the BBC1 series.
As well as confronting himself, the actor encountered dozens of past foes at Olympia 2 in Kensington, west London.
They included the many incarnations of Daleks and Cybermen from throughout the ages. More modern foes include Judoon and Weeping Angels, while Ice Warriors from Patrick Troughton's era as The Doctor and the Giant Robot from the Tom Baker era also feature.
Matt, 28, had a cast made of his entire face, to allow model makers to put together his double over a two month period, which stands guard outside the Tardis.
The star straightened his model's bow tie as they met. Smith said: "I think he's sort of a bit musclier than I am!
"It's a surreal experience to have an image of yourself in 3D. So weird but one of the wonderful privileges of this particular job - you get rather mad experiences."
The star had his face coated in a plaster of Paris-type substance to create the head. He said: "It was quite a harrowing experience. My face was completely covered and I had just like a couple of straws for my nostrils. It was pretty grim."
The interactive walk-through exhibition also includes an interior of the Tardis, the Pandorica which featured in the most recent series, and specially filmed sequences featuring Smith.
The exhibition is scheduled to run for the next few months. Further details are available from www.doctorwhoexperience.com.
