Headhunters (original Norwegian title Hodejegerne) is a critically-acclaimed 2011 Norwegian thriller directed by Morten Tyldum starring Aksel Hennie, Nikolaj Coster-Waldau and Synnøve Macody Lund, based on the 2008 Jo Nesbø novel of the same name. There are currently plans for an American remake.
The following weapons were used in the film Headhunters:
Ove Kjikerud (Eivind Sander) own a Beretta 92 Steel I, which he keeps in his refrigerator. The gun is shown seamlessly transitioning from firing blanks to firing live rounds. Roger Brown (Aksel Hennie), Clas Greve (Nikolaj Coster-Waldau) and Diana Brown (Synnøve Macody Lund) also get their hands on the pistol during the course of the film.
While Googling Clas Greve, Roger comes across a few pictures of Clas from his army days, including one where he's holding an M4A1 carbine with an underbarrel M203 Grenade Launcher.

The guys around him also sport American 82nd Airborne patches on their arms.
