On 28 May, the following important behind-the-scenes events were known to have occurred:
- 1964 - The BBC's Director of Television, Kenneth Adam, sent a memo to his Controller of Programmes for Television, which soon went down the chain through Sydney Newman to Donald Wilson, and ended up on the desks of producer Verity Lambert and story editor David Whitaker. The concern from on high? Even Adam's 3½-year-old granddaughter knew that it was "stupid" of the First Doctor and his companions to separate in a dangerous situation, such as they did in last Saturday's episode. Adam wanted the production team to "exercise more discipline" in the writing so that the programme's stars don't act like idiots. Otherwise, he feared that the programme's longevity will be at risk.
- 1965 - "The Death of Doctor Who" was recorded at Riverside Studios 1. (TCH 5)
- 2013 - Recording for 1963: The Space Race took place at The Moat Studios.
