Missing in the film is Junuis Du Pont, the man who has been taken to the cleaners by Auric Goldfinger. Also missing are Goldfinger`s backers, SMERSH, as well as the use of a train for the heist. Instead he is backed by the Red Chinese, who also have supplied him with an atomic bomb. Also, a vital scene in a New York hospital where Bond and Tilly Masterton are being held was removed because Oddjob killed Masterton in the film.
The way that Goldfinger has planned to poison the town is also different in the book than in the film. In the book he places a diluted substance in the water, which will knock out everyone. In the movie he puts it into the air. And finally, the most memorable scene in the film , the laser scene, was originally a huge industrial saw used to torture Bond. In the book it had to be a saw because commercial use lasers, as a rule, hadn`t been invented yet.
