Dimensions in Time is a charity special crossover between the British science fiction television series Doctor Who and the soap opera EastEnders that ran in two parts on 26 and 27 November 1993. It was filmed on location at Greenwich and the EastEnders Albert Square set, situated at Elstree Studios in Borehamwood, Hertfordshire. It featured all of the actors to have played the Doctor still alive, many of the character's companions and several of the EastEnders stars of the time. Produced for the Children in Need charity following Doctor Who's cancellation in 1989, this special was the only drama broadcast in celebration of the show's 30th anniversary.
