The Mist (2007)

A dense mist descends on a small town after a storm. A few dozen people in a grocery store discover that the mist is home to terrifying creatures. They work together for a while, but soon the ravings of the local nutjob begin to make sense to some of the people so now there's danger from without AND within.

It's pretty effective when not depending on prideful contrariness. That device of people being so sure that warnings are deliberate lies always makes me crazy. I must concede, however, that the last 6 years or so have proven that simply loudly denying verifiable truth really really works on some people. That's scarier than any monster lurking in the fog.
