I’m not a purist like some readers when it comes to book-to-movie adaptations. I believe it’s okay to change certain elements, or cut out scenes if the time constraints don’t allow for them.
However, Hollywood has a bad habit of fixing things that aren’t broken.
They make badass characters completely pointless (Annabeth in the Percy Jackson films), they remove all humor from a story that is supposed to be a comedy ( Hitchhiker’s Guide to the Galaxy movie), or they just straight up give the story an icepick lobotomy (Cat in the Hat).
The main reasons movies like these fail is because those behind the movie don’t care about what made the original source material great in the first place. They just want to cash in on the book’s success.
As a result, a lot of these movies make a bit of money, then vanish into the ether, never to be watched or spoken of again.
The best book-to-movie adaptations I’ve seen are usually the ones where the author has had at least some influence on the production.
Without J.K. Rowling’s input as a consultant, Alan Rickman wouldn’t have known how to approach the character of Professor Snape and the twist that Lily was actually the love of his life would have come completely out of left-field.
Gillian Flynn wrote the screenplay for Gone Girl and, as a result, it was able to successfully juggle the action, intrigue, and social commentary of the book. If this had been written by someone other than the writer, this would have likely been a train-wreck, or a dime-a-dozen thriller rather than a brilliant commentary about the media and modern relationships.
Especially since Hollywood doesn’t seem to know how to write social commentary anymore.
The Fault in Our Stars was also a brilliant adaptation that captured the humor and heartbreak of the book. John Green was a strongly involved in the making of the movie and, of course, it became a big hit unlike many YA novels that are made into film (excluding Hunger Games and Harry Potter, obviously). I believe this mostly had to do with the cast and crew’s willingness to listen to Green’s input instead of interjecting an unnecessary love triangle or “hip lingo.”
If the filmmakers haven’t bothered to read the book they should, at the very least, have an understanding of why these stories resonate so strongly with readers, and respect authors as fellow artists rather than brushing them off.
Authors may not be able to write a screenplay of their work, but they do understand the material. They spent months, maybe even years, with these characters and settings.
They’ve had to kill their darlings before so they understand that some things have to be changed for a visual medium. However, their input could prevent something important from being chucked in the bin.
Some writers may not be well acquainted with the world of cinema, but that doesn’t mean their views should be discounted. After all, they were able to make thousands, or even millions, of dollars without A-list actors, exotic sets, or fancy cinematography.
Think about that for a second.
Also, stop making movies about nonfiction self-help books.
