20 Things You Didn't Know About The Prestige
17. The Movie Made One Massive Change From The Original Novel
It's borderline impossible for a director to take a novel and translate it word-for-word onto the screen. Movies just have to be constructed differently to books, and the same was true when Nolan was tasked with adapting The Prestige.
The movie makes several changes to the source material (like altering Angier's first name from Rupert to Robert), but one of the biggest tweaks it made was the decision to omit a modern-day subplot involving the descendants of Angier and Borden.
In the book, Angier and Borden's great-grandchildren are involved in the story, with parts of their lives being interspersed with the events of the past. However, Nolan chopped out these present-day segments entirely, possibly for the purpose of streamlining the novel to fit within a two-hour runtime.
