  • Producer David Richardson recalled that the idea for Out of Time 2 - the teaming up of the Tenth and Fifth Doctors - was discussed even before Out of Time 1. It was inspired by Time Crash and the familial relationship between David Tennant and Peter Davison. The idea was returned to in 2020 when both actors were available during the Coronavirus lockdown, by which point Out of Time 1 had already been recorded. (BFX: The Gates of Hell)
  • David Llewellyn re-watched Time Crash to get an idea of the relationship between the two Doctors. (VOR 147) Time Crash was also used as a point of reference for Out of Time 1, though exclusively for the Tenth Doctor. (VOR 137)
  • Because the multi-Doctor element took precedent, the Cybermen were a later addition to the story. The involvement of the Daleks in Out of Time 1 aided the decision to pit two Doctors against another popular recurring foe. (BFX: The Gates of Hell)
  • Numerous discussions were had about which model of Cyberman would be used in the story. Ultimately, it was decided to use the CyberFaction from The Invasion. (BFX: The Gates of Hell) Similar discussions had been held about the Daleks in Out of Time 1, where it was decided to use both new and old. (VOR 137)
  • Llewellyn's script was inspired by a trip he made to the Paris Catacombs in 2018. The entrance to the Catacombs was at a place called the Gates of Hell. (VOR 147)
  • This story was recorded remotely on 30 June 2020.
