The top image is the brand spanking new poster for M. Night Shyamalan's The Happening starring Mark Wahlberg which hits theaters in June 2008. It's about an environmental apocalyptic crisis, and comes with the tagline, “We've sensed it. We've seen the signs. Now it's happening.”
The same tagline could have been used for the seminal apocalyptic 1983 nuclear holocaust film The Day After, which I've screengrabbed below.
In either case, don't bother taking the highway out of town. It ain't gonna get you far.
