The author of the iconic James Bond series, Ian Fleming, traveled to his second home in Jamaica every year and wrote a James Bond novel. He started in 1952 and now his character has become a cultural phenomena. With twelve novels and two short story collections there is a lot of material to pick from. What can be adapted from each novel and put into the film? It's tough. But there are a few that come close to their source material.
1. Casino Royale
What They Kept: Surprisingly most of the novel is in the movie just modified for todays audience. But the most shocking things that many people thought weren't going to be in the movie were. One of those things was the torture scene. Yes, that scene in the movie where Le Chiffre hits Bonds testicles with a rope is in the original novel. Plus they kept the part where Vesper gets put on the road so Bond could crash. They even kept the character of Gettler, the guy with the one dark lens in his glasses.
What They Got Rid Of: The game they play in the movie is Texas Hold 'em poker. The original game that was played in the novel was Baccarat. Also, some of the ways the villain tries to sabotage Bond have been changed.
What They Added: The first 40 minutes of the movie was all added. In all fairness the plot of the movie doesn't kick in until the 50 minute mark. All of the extra material was to set up why they needed to go after Le Chiffre and to set up Daniel Craig as Bond.
2. Dr. No
What They Kept: The first ever Bond movie but the 6th novel. This was another first by having Bond carry his famed weapon of choice, the Walther PPK. Both the novel and book address this. Ian Fleming was contacted by a fan of his who was a gun expert. He wrote to Mr. Fleming that Bond shouldn't be carrying a .25 caliber Beretta, but the more powerful Walther. They also had the same plot of the book along with the fake dragon that everyone is scared of. And Honey Ryder is also in the book, and appears the same way she does on screen.
What They Got Rid Of: They stripped away Honey Ryder's character. She is tough and more capable in the book than in the movie. She also has a lot more to do, and is somewhat essential. The reason Dr. No has metal hands was changed. In the book his hands were cut off by Chinese Triad gangsters. In the movie he says its because of a radiation accident. And the biggest thing they took out was the giant squid that attacks James Bond. After No captures Bond and Ryder, he makes Bond go through a series of obstacles. The last one escaping the squid monster.
What They Added: A character by the name of Professor Dent was added into this movie. He was a turncoat working for Dr. No. He was used just as another threat Bond had to dispatch. Also, the introduction of SPECTRE.
3. From Russia With Love
What They Kept: A huge majority of the book is prevalent throughout the movie. Though it is significantly toned down or changed around due to editing problems. The major thing that was kept was the fight on the train between Bond and Red Grant. Another big thing was the introduction of the attache case that is presented by Major Boothroyd aka Q. All the special equipment that is in the case is mentioned in the book.
What They Got Rid Of: Mostly character development between Bond and Kerim Bay was left out. Plus most of Grants back story was cut. Including Grants story, they got rid of the main antagonist force called SMERSH. A Russian agency sort of similar to SPECTRE. And the original ending was Bond getting stabbed by Rosa Kleb and blacking out. Ian Fleming wasn't sure if he wanted to continue writing so, he left that in the novel as a way out.
What They Added: SPECTRE was put into the franchise to bridge each movie. It was the main force Bond fights throughout his early film career. Blofeld makes his first appearance in this movie. They also added a helicopter chase and boat chase to make the movie more exciting. And, they added the maze pre-credit scene as well.
4. On Her Majesty's Secret Service
What They Added: They added in a few fights scenes here and there. Like the one early on in Tracy's hotel room. They added the part in the car chase where Bond tries to lose Blofelds men in the race track. There is a scene where Bond cracks a safe thats not in the book.
What They Got Rid Of: There were more moments in the book where Bond was disguised as Hilary Bray, but they were taken out. Along with two chapters explaining Blofelds plan.
What They Kept: Just about everything really. This is the most faithful adaptation. Mostly everything you see in the movie was in the book. The only thing is the movie jumbles up the order of events. Like Bond and Tracy don't fall in love technically until the end of the book. Also, the events in the beginning of the movie are the same as in the book. The book uses a flash back/forward technique where after the fight on the beach he gets taken to Drago. The movie has Bond get captured a little later on after the pre-credit beach sequence.
