The Darkest Hour is a science-fiction film directed by Chris Gorak and produced by Timur Bekmambetov (Wanted, Abraham Lincoln: Vampire Hunter) about a group of American tourists who are trapped in Moscow when the world is invaded by invisible, energy-consuming aliens.
A Militsiya (Police) officer fires a Makarov PM at one of the aliens in the beginning, to no avail as it disintegrates the bullet without causing any damage. During the movie several characters are seen with PM pistols, mostly holstered.
Matvei (Gosha Kutsenko), leader of the resistance group carries a Stechkin APS as his personal sidearm, firing it (sensibly) in semi-automatic at the aliens near the ending.
Two AKS-74 rifles are seen in the trunk of a police car that Sean (Emile Hirsch) and Ben (Max Minghella) hide behind after obtaining flares and a map. Later one of the resistance fighters, Sasha (Nikolay Efremov), is seen using AKS-74.
When Sean and the tourists head to the bay they encounter resistance fighters Matvei (Gosha Kutsenko) and Yuri (Artur Smolyaninov) who are both seen with AK-74M rifles to battle the aliens. Yuri fires his AK-74M at the aliens in the final battle.
When the tourists enter the U.S. embassy, dozens of M4A1 carbines are seen scattered next to empty shell casings. Skyler (Joel Kinnaman) picks one up and wildly fires it as rubble drops in front of him and the American tourists. Skyler carries the M4 with him after he leaves.

Mk. 18 Mod 0
In the top part of the U.S. embassy, a Mk. 18 Mod 0 can be seen on the box the tourists pass by.
A Barrett M99 can be seen at the top bunker of the U.S. embassy without an optic attached. When the tourists take a view outside, they use what appears to be the rifle's scope as a binocular.
