Movies are escapist, and none more so than disaster flicks. So of all the catastrophes that Hollywood has put before you, which strikes you as the most devastating? Does a threat from beyond (The Day the Earth Stood Still) freak you out more than the Ebola virus (Outbreak)? Does a devastating reality (Titanic) convey more dread than a "what if..." scenario (Deep Impact)?

Decide which disaster ranks as the best worst case scenario. There are sixteen hells to chose from.
