20 Things You Didn’t Know About On Her Majesty’s Secret Service (1969)

Ian Fleming left Tracy out of the explosive final battle at Piz Gloria in his 1963 novel, so the filmmakers emphasised the emotional stakes in the plot by having Blofeld hold her hostage at his mountaintop lair in the film adaptation.
However, Peter Hunt was dissatisfied with Richard Maibaum’s script for Diana Rigg’s scenes with Telly Savalas, so he hired screenwriter, Simon Raven to produce “sharper, better, and more intellectual” "additional dialogue" for them.
Memorably, Tracy quotes an amended stanza from James Elroy Flecker’s play Hassan: The Story of Hassan of Baghdad and How he Came to Make the Golden Journey to Samarkand (1922) as she lures Blofeld out into the open for the attack coordinated by James Bond and Draco.
