Although the 1990 movie Misery features a disturbingly brutal scene between Annie and Paul, the Stephen King book contains an even more gruesome moment, which was changed for a very specific reason. Rob Reiner's Misery is based on Stephen King's 1987 novel of the same name about Paul Sheldon, a famous writer of successful Victorian romance novels, which feature the character Misery Chastain. After an accident, he finds himself bedridden in the home of Annie Wilkes, his number one fan. The plot takes a dark, gory turn when Annie learns that Paul has killed off her favorite character Misery in his next novel.
