coma moviesYou'd think there'd be a lot more comatose characters in movies, like the heroine of "If I Stay" (opening Aug. 22), a teen played by Chloe Grace Moretz who must choose between life or death after a devastating accident results in an out-of-body experience.

After all, the coma is a blunt but effective dramatic device, one which forces the rest of the characters (and sometimes, as in "If I Stay," the coma patient herself) to decide what's really important in their lives. The coma's suspension between life and lifelessness also makes it a useful tool for horror filmmakers.

And yet, there really aren't that many films that make good use of the coma. Maybe filmmakers think it's a cliché, or too melodramatic. But that means that the films that do make effective use of comas are that much more memorable. Here are 14 of them, most of them guaranteed to make you cry or to scare you out of your wits.
