It’s Allies vs Nazi Zombies in Debut Trailer for WWII Horror Flick ‘Overlord’ (VIDEO)

J.J. Abrams' production house Bad Robot has brought many things to the screen over the years, but the one thing they haven't explored is a film with an R-rating. That all ends this November when Overlord hits theaters, a film that takes the concept of Nazi genetic engineering to some strange and scary places.

Sure, the notion of a Nazi zombie film is far from original, especially in the last few years as the zombie thing has blown up in popularity, but this seems to be a slightly different animal. First rumored to be a part of the Cloverfield universe that Abrams holds so dear, the film is actually about a squadron of Allied soldiers behind enemy lines during WWII who stumble upon a laboratory where Nazis are experimenting with all manner of monster creation.

Though Abrams is only producing the film—it's directed by Julius Avery—he's been promoting the hell out of it, even referring to it as "batshit crazy" and "super fun" during a presentation at this past spring's CinemaCon. If this first trailer is any indication, I think he might be telling the truth. For once. Overlord is set to invade theaters—and your nightmares—on November 9.
