Behind the scenes

Though there has yet to be a "Halloween Special" of Doctor Who or its televised spin-offs, there have been episodes that premiered either on or around Halloween. The only Doctor Who episode to officially air on Halloween was series 9's The Zygon Invasion. Previously, the opening episode of the season 2 serial Planet of Giants aired on 31 October in 1964, although this was years before the predominantly American holiday began to be acknowledged in the United Kingdom.

The penultimate series 8 episode, Dark Water, aired the day after Halloween on 1 November 2014. A review of the episode from The Independant cited it as being "everything you could ask for from a Doctor Who finale the day after Halloween", a reference to the episode's particularly morbid subject matter not being at all out of place around the holiday.

In spin-offs, the first episode of K9, Regeneration, was broadcast on Halloween in 2009.

Televised Doctor Who was set to enjoy its first set of Halloween specials via The Sarah Jane Adventures, which was planned to have four such specials appear some time after its truncated fifth series. As with the remainder of series 5, the specials were never produced due to the death of Elisabeth Sladen.

Doctor Who got its Halloween special on 31st October 2021. It was called "The Halloween Apocalypse "and introduced john bishop as the new companion Dan Lewis.
