1. The location of the original story is in Detroit, and the film is in Northern California, mainly for the purpose of better viewing.
2. The timeline of the original work is much longer. In the film, it only took a short time for the suicide incident in Russia to be reported on TV to spread to the United States. In the novel, the spread of large-scale suicide took longer, and it was not reported on TV. The form of the film is a rumor from the people. It was not until later that people realized that it was really not quite right. This adaptation is to allow the film to have more space to tell the story behind.
3. Jessica played by Banana Sister, Malorie's sister is Shannon in the novel. After the disaster, the two returned home and hid for three months until Jessica accidentally saw the spirit commit suicide in the bathroom. The movie was adapted for the reasons mentioned above and died on the way home.
4. There are not so many lunatics in the original book. They just guessed that those mental patients would not commit suicide even after seeing the spirit body. As a result, Gary came to confirm this guess. On the contrary, there are a lot of lunatics in the movie talking about purifying the world.
5. The names and endings of some supporting characters in the book are slightly different. For example, Douglas, the uncle who loves to get drunk and quarrel with Malorie, does not have this character in the novel. The novelist Charlie is called Don in the original book, who lives longer and has a greater effect. On the contrary, the black Tom is not so useful in the original book. He was killed by Gary when Malorie gave birth. Malorie raised the children alone, which is why she called them Boy and Girl, because she felt that everything else was extravagant and useless except to survive.
6. In the original book, the two children were blindfolded from birth. They have never taken them down to train them to move without vision.
7. In the original book, Malorie and the children trained for four years before daring to go boating to the shelter. (So don't talk about the logic, how many details do you want in the two-hour space, you can make up for this by yourself)
8. In the original book, the effects of the birds are highlighted. They are used as a device to detect the presence of spirits. The birds in the bird box eventually go crazy during the journey. There is also a scene in the original book: when they were about to reach the end, hundreds of birds went crazy and died, and a rain of dead birds began. In the movie, the symbolic meaning of the birds is greater. There are also dogs in the original book. Some were found to have not gone crazy with their dead owners, but they were also found to have gone crazy. Therefore, it can be inferred that although dogs are not immune, they may be more resistant than humans.
9. The ending of the original book is darker and creepy. After they arrived at the refuge, Malorie gradually discovered that many blind people actually had their eyes deliberately stabbed or gouged out to prevent the invasion of the spirit body. She suspected that she and her two children might be forced to be blinded.
The last thing I want to say is that I think this translated name is not as good as the original name. Bird box is actually a pun. It refers to the box of birds in the hands of the heroine. Does it actually symbolize human beings? What about the fate of being locked in a room? I thought of this because it felt like a birdcage when I looked at the ceiling in the last scene of the refuge.
