Doctor Who fans from all over the world converged on the ExCeL this weekend to celebrate the show’s 50th anniversary.

They were treated to question and answer panels featuring actors past and present, including five who have taken on the iconic Doctor role over the years.

Colin Baker, who played the Doctor between 1984 and 1986, was surprised by the show’s longevity.

He said: “I never quite realised that 30 years later I would be sitting here having five Doctors after me already.”

Many fans queued up to have photographs taken with their favourite stars and gather as many autographs as possible.

Luke Browne, from Portsmouth, said: “I met Jenna Coleman, I got a photo with her and her autograph. She was really nice.”

Interactive sessions included a stunt school, walking like a monster and designing your own villain.

Fans could also enjoy a special effects show, with the show’s SFX co-ordinator Danny Hargreaves demonstrating how to explode Daleks and Cybermen and alter the weather.

Actors Matt Smith and Jenna Coleman and the show’s lead writer Steven Moffat were presented with a Guinness World Record certficate in front of thousands of fans to celebrate the 50th anniversary episode being the world’s largest simulcast of a TV drama.

It was shown in cinemas and on television screens in 94 countries.
