It's rare to see Norman Reedus, a.k.a. the Grand High Emperor of Bad-Assness from "The Walking Dead," engaging in anything so undignified as an onscreen panic attack.

So when we tell you that he's having one in this newly-released footage from "Air," you may trust that whatever's happening must be really bad.

io9 has the exclusive clip of the scene, which they refer to as "the most pants-wetting moment" from the film.

Having not seen it ourselves, we can't speak to the "most" part -- but the pants-wetting? Um, yes. Confirm. You go ahead and watch it; we will be right here, putting on a fresh pair of pants.

The movie, which is set in a future where the surface of the Earth has become uninhabitable, stars Reedus and Djimon Hounsou as a pair of maintenance workers charged with the care and keeping of a bunch of cryogenically-frozen scientists in one of several underground facilities.

An official trailer also dropped this week. Check it out below:

"Air" will be available on demand and in select theaters starting tomorrow (August 14.)
