'Texas Chainsaw Massacre' has to be at or near the top of the list. To this day I get chills watching it.

I can't remember the name of it. I watch it sometime ago. It was about a plane crash in the mountains and the passengers were straving. The living began to eat the dead. It was based on a true story. All I know is that film really screwed me up for a week. Other then that, nothing has done much.

Are you possibly talking about Alive?
