By the time Daniel Craig ("Knives Out," 2019) became James Bond, they had almost run out of source material. In fact, his first Bond film, 2006's "Casino Royale," is his only one directly based on a novel.

The character of Mr. White -- played in the film by Danish actor Jesper Christensen ("The Debt," 2010) -- does appear in that book, but not by name. In both the book and the movie, he is [spoiler alert for the 16-year-old movie and 69-year-old book] the assassin who kills the main villain, Le Chiffre (played by Mads Mikkelsen, "The Hunt," 2012). In the book, however, he doesn't get a name.

They pretty much had to name him in the movie because they were expanding his role significantly. The bit at the end of the movie that sets up the plot of the sequel, a bit that centers around Mr. White, does not appear in the book.

That's essentially where the Craig movies depart from the source material entirely. (Though 2008's "Quantum of Solace," the second Craig film, took its name from a Fleming short story, the plot is entirely original.)

In "Quantum of Solace," viewers learn that Mr. White works for the criminal organization Quantum. This, too, was created specifically for the films. It was made to replace SMERSH, the organization Bond frequently fought in the novels. It was a part of the government of the Soviet Union and thus was in need of an update.
