EastEnders

EastEnders was a television show broadcast in the United Kingdom, Earth, during the late 20th century and the 21st century. In summer 2007, with the new "ghost" craze sweeping the planet, one of the killed-off characters, Den Watts, was brought back to the show in ghost form, using one of the ghosts which materialised during that period. It was later revealed as a new form of Cyberman. (TV: Army of Ghosts)

Cross-overs with Doctor Who

 * Though other stories portray EastEnders as a television soap, the Brief Encounter story Mistaken Identity by Gary Russell and the Doctor Who mini-episode Dimensions in Time cross over EastEnders with the Doctor Who universe. A line in First Frontier dismissed that adventure as a dream.
 * The comic adventure Happy Deathday seems to take place, in part, in the EastEnders universe. This is later revealed to be a video game being played aboard the Doctor's TARDIS.
 * In the comic Tooth and Claw, the Eighth Doctor refers to "Albert Square", the location of the series (although he might have meant another Albert Square).

The Brilliant Book 2012

 * According to The Brilliant Book 2012, a book that contains non-narrative based information, William Shakespeare was the head writer of EastEnders in an alternate timeline.
