Here's the trailer for the movie adaptation of Stephen King's The Mist. The black guy gets killed first, that's original.
After a violent storm attacks a town in Maine, an approaching cloud of mist appears the next morning. As the mist quickly envelops the area, a group of people get trapped in a local grocery store. The people soon discover that within the mist lives numerous species of horrific, unworldly creatures that entered through an inter-dimensional rift, which may or may not have been caused by a nearby military base.
Ho hum. I was hoping it'd be more like that Simpson's episode with the fog that turns people inside out (5:17).
