The book-to-film transformation has been a crucial pillar of the movie-making business for decades. With thousands of readers having already turned the pages of an original idea, a firm audience already exists for the source material, compelling Hollywood to buy out the rights and get production rolling on a more visual incarnation.
Adaptations are a sure-fire bet for any filmmaker looking for a script to translate, but moving it to the screen is more complicated than you'd think. Concessions need to be made, casting needs to be handled carefully and moving too far in the wrong direction can draw the ire of both the community and the original author.
Be that as it may, many a film has been able to overcome the dangers posed by ignoring the source material. They've diverged from the original stories, using them more as inspiration rather than straight gospel. As we've seen through the decades, this has resulted in some truly excellent film productions that transcend the original sources they came from.
All of the following are standout films that ditched their literary sources and became hugely successful as a result - even if the original authors didn't always agree.
