There's all kinds of people in this world, and no matter how much we try, we always seem fascinated by cases of strange killings and messed up crimes. There are murderers, and then there are people who are a special breed of evil, or just plain insane. They usually end up inspiring screenplays for movies though.

Here are some famous murderers and the movies they inspired!
