Trivia / Doctor Who S36 E7 "The Pyramid at the End of the World"

• Distanced from Current Events: The Manchester Arena suicide bombing took place the Monday before this episode premiered, so dialogue noting terrorism as one of the many threats Earth faces was cut.
• Recycled Set: The UN plane our heroes take to Turmezistan uses the same set as Boat One from "Death in Heaven".
• Troubled Production: Steven Moffat told Doctor Who Magazine that with only days to go before shooting on this story began, his mother suddenly took ill and died — he was working on the final draft next to her hospital bed. Had this personal tragedy not happened, he would have had time to hash out the details of and refine the script with co-writer Peter Harness. Said Moffat, "Peter deserved better from me, frankly."
• What Could Have Been: Kate Stewart was meant to be in this episode, but Jemma Redgrave had a scheduling conflict with Holby City.
• You Look Familiar: Actor Tony Gardner, who plays the scientist Douglas in this episode, had previously appeared as the villainous Stapleton Petherbridge on the Big Finish Doctor Who story "The Wrong Doctors".
