Over Easter weekend the 3rd and 4th of April 1983 the BBC held the biggest Doctor Who event ever to celebrate the 20th Anniversary of the programme. The BBC expected 10,000 people a day. They got 30,000. We travel back to 1983 using extensive video footage of the entire event plus interviews with those people who were there – both the organisers and the attendees. In this landmark video we feature Heather Hartnell, Patrick Troughton, Jon Pertwee, Tom Baker, Peter Davison and a host of celebrities and production staff from Doctor Who in what might be for some… The greatest show in the galaxy!
