When you read, you are creating your own movie. Your brain is more engaged and invested in a book. It is a very active process, combining the words you are seeing, processing, and understanding to create a full-color, vivid, on-demand movie in your mind. You are director and producer. You are in charge of makeup and costumes. You choose the locations and scenes. All of this in a split second.
That's why reading makes you smarter. Not only are you able to learn new words, but you are also engaging so much of your brain in sequential, systematic, and parallel ways - many times all at once!
There will never be a better movie-maker than your own imagination.
Some books to try instead of the movie:
The Handmaid's Tale by Margaret Atwood
One of my top 10 books, the story presents a challenge to the screen because it is primarily internal monologue. While the film and television series are true to the dystopian nature of the story, it is impossible to capture the parallel thoughts and feelings of the protagonist and the other handmaids as told in the double narrative-style of the book.
The Giver by Lois Lowry
Another one of my faves, this is the first book in a quartet. While the film adaptation, again, presents the general idea of the book, the fact that one character was given a much bigger part in the film (Streep's characterization of the Chief Elder) in order cash in on her star power doesn't sit well with me. The book is about exploring feelings, making decisions, and actions bringing consequences.
The Lost Weekend by Charles R. Jackson
The film version was highly acclaimed, nominated for seven Academy Awards and winning four. What is missing here, however, is the raw and visceral pull of alcohol on the main character. It consumes him, drives his behavior, and pulls the reader in opposing directions of disgust and sympathy for him. Thought of as the seminal American novel on addiction, this desperation cannot be captured on film. That, coupled with homosexual overtones, makes this 1944 novel a must-read.
These are just three of my pics for you. Let me know of other books-into-films you have experienced, and what your impression on the comparison was.
