Story Notes

 * This story marks the beginning of the quest for the Key to Time, with all stories in Season 16 being linked around this theme. This was the first time a story arc encompassed an entire season.


 * The original credits list the White Guardian as simply "The Guardian." This may be a hint at a suspicion the Doctor voices at the climax of "The Armageddon Factor," that he and Romana have along been working for the Black Guardian disguised as his more benevolent counterpart.


 * The Key to Time prop was created by visual effects designer Dave Havard.


 * New companion Mary Tamm had attended RADA with her predecessor, Louise Jameson.


 * Originally, the shortened form of Romanadvoratrelundar's name was to be "Romy."


 * On the night before the last day of recording The Ribos Operation, Tom Baker was bitten on the left side of his upper lip by a dog belonging to Paul Seed (who played the Graff Vynda-K). Publicity photographs from late April show Baker with a plaster cast on that lip, and the wound had to be concealed with makeup, much to the actor's discomfort. The scar was quite noticeable on screen, and also throughout most of this season and the next.
