Dimensions in Time is a charity special crossover between the British science fiction television series Doctor Who and the soap opera EastEnders.
The special was broadcast in two parts on 26 and 27 November 1993 and was filmed on location at Greenwich and the EastEnders Albert Square set.
The special was produced for Children in Need following Doctor Who's cancellation in 1989 and was the only original story broadcast in celebration of the show's 30th anniversary.
She wants to put us out of action, lock us away in a dreary backwater of London's East End, trapped in a time-loop in perpetuity.
The Doctor finds a newspaper showing the year to be 1973, but before he can make any more conclusions, the Rani causes time to jump.
The Third Doctor and Mel Bush appear from the time jump, and question an older Pauline Fowler and Kathy Beale on when they are.
As Mandy Salter tries to stop the Rani, Captain Mike Yates of UNIT arrives in Bessie to save the Third Doctor and take him to the Brigadier who is waiting for them.
The array of aliens summoned to Walford by the Rani included: an Aldeberian (Zog), an Argolin, a biomechanoid dragon, a Cyberman, a Mawdryn mutant, Lord Kiv, a Mogarian, an Ogron, a Plasmaton, the Sandminer robot D84, a Sea Devil, a Stigorax (Fifi), a Tetrap, a Time Lord, a Tractator, a Vanir and a Vervoid.
Dimensions in Time has received almost universally negative reviews and is often highlighted as a particular low point of the Wilderness Years: the period between Doctor Who's 1989 cancellation and the 2005 revival.
