Looks like we picked the wrong week to quit smoking. Whether it’s an imminent natural disaster, a towering inferno, a cruise liner steaming towards an iceberg, or an airplane full of panic, we want your top 10 disaster films, with one rule: they must be set within the Earth’s atmosphere (we’ve covered outer space in earlier Showdowns). What more perfect genre was the medium of film made for than the disaster flick? From eruptions and earthquakes to wildfires and floods, disaster movies thrust us deep into the great nail-biting moments of history and fiction, and the spectacular heroics that ensue. We’ll never let go, Jack, we’ll never let go.
