From NetFlix:

In this creepy thriller based on Stephen King’s book, Annie Wilkes (Kathy Bates) rescues her idol, romance novelist Paul Sheldon (James Caan), after a horrible car accident. But she morphs from nurturing caregiver to sadistic jailer upon discovering that Sheldon plans to kill off his literary heroine, Misery, in his next volume. Bates’s disturbing performance as the psychotic Annie netted her a Best Actress Oscar.

The book is quite good especially compared to the movie. The movie vaguely resembles the book but still offers the same roller coaster ride. It’s just fun at a B level. Kathy Bates as the crazy captor and James Caan as the captive are a hoot. Bring along your strong stomach for some of the violence.
