Doctor Who visits Trafalgar Square

The stars were seen with a group of actors dressed as armed police officers while a crane lowered the Doctor’s trusty police box to the ground.

Show bosses have stayed tight-lipped about the plans for the special episode which is rumoured to be a 3D extravaganza filled with familiar faces from the history of the show.

Last week, they confirmed that former Doctor Who actor Christopher Eccleston had turned down the chance to appear in the episode.

The actor, who played the ninth reincarnation of the timelord when the BBC revived the show in 2005, met writer Steven Moffat to discuss the anniversary.

“Chris met with Steven Moffat a couple of times to talk about Steven’s plans for the Doctor Who 50th anniversary episode. After careful thought, Chris decided not to be in the episode. He wishes the team all the best”, said a BBC spokeswoman.

At least one living former doctor – David Tennant – will return for the one-off show after it was announced he and Billie Piper, who played companion Rose Tyler for two series, will join the current Doctor, played by Matt Smith, in the programme.

But fans might still get the chance to see Eccleston’s portrayal of the Doctor as show bosses are rumoured to be planning to use old footage of previous incarnations for the special show.

This will also please some Irish fans.

Recently the Deparment of Justice sent out a press release on behalf of the Justice Minister Alan Shatter which mentioned the new series of Dr Who.

Irish Mirror journalist Cathal McMahon tweeted a screenshot of the email.
