Children of Men is a 2006 science fiction action thriller film loosely adapted from the P.D. James novel of the same name and set in a future where women have become infertile and the human race is on the verge of extinction. Clive Owen stars as a government bureaucrat in the now-totalitarian state of Britain, who is asked by his estranged wife to protect a young woman who could hold the key to the human race's future. The film was directed by Alfonso Cuarón.
The following weapons were used in the film Children of Men:
A Beretta 92F is one of the guns seen on the table during the farmhouse meeting. Two United Kingdom Police officers who pull over the car before being shot by Luke (Chiwetel Ejiofor) also carry Berettas as their sidearms.
Taurus PT92
During the meeting in the farmhouse, a stainless Taurus PT92 can be seen lying on the table.
Heckler & Koch USP
During the meeting in the farmhouse, a Heckler & Koch USP can be seen lying on the table. Syd (Peter Mullan), a Homeland Security Immigration Control officer also carries one as his sidearm, using it to threaten Theo and Kee when he decides to betray them for a reward.
Heckler & Koch UMP-9 can be seen in the hands of 'Fish' resistance fighters and British Army soldiers.
Rifles
Heckler & Koch XM8 (Airsoft Replica)
Airsoft replicas of the H&K XM8 rifle with dummy sights from the G36K appear throughout the movie in the hands of British police officers guarding detained refugees and later at the Bexhill refugee camp.
M4A1 Carbine
An M4A1 Carbine, fitted with an Elcan optical sight, is first seen in the hands of a 'Fish' gunman when Theo Faron (Clive Owen) is kidnapped by the resistance group. Later, during the action sequence at the Bexhill refugee camp, a female 'Fish' is also seen with an M4. While it would be more likely in reality for the gun to be a Diemaco C8A1 Carbine, Colt Canada did not sell to civilian companies (including film armorers) at the time this film was made, so it would be impossible to use one in the film. Another M4A1 carbine, equipped with an M203 grenade launcher, tactical light, and an AN/PEQ-2 IR designator, is used by Luke (Chiwetel Ejiofor) when his forces arrive at the Bexhill refugee camp.
Kalashnikov Variants
Two types of Kalashnikov rifles appear in the film. Modernized versions with plastic furniture are used by Tomasz (Jacek Koman) and Sirdjan (Faruk Pruti), while older versions with wooden stocks are seen in the hands of refugees throughout the film.
At the Bexhill refugee camp, one of the resistance fighters carries a G36C which he fires at approaching British troops. Shortly after, a British Army squad leader who orders his men to cease fire is also armed with a Heckler & Koch G36C. Prop G36Ks can also be seen in the hands of refugees during a funeral march.
L85A1
British Army soldiers throughout the film use L85A1 rifles (identified by their round charging handles). They are fitted with SUSAT scopes, however, on closer examination, they are actually of Swedish rather than British origin based on the different designs of their mounting base. They are most prominently seen when the military invades the Bexhill refugee camp.
Machine Guns
Heckler & Koch HK21
A Fish at the farmhouse meeting is briefly shown brandishing a Heckler & Koch HK21 machine gun.
L7
An L7 machine gun is seen mounted at an army checkpoint leading to the Bexhill refugee camp. Another L7 is mounted on the commander's hatch of the Chieftain tank seen towards the end of the movie.
PK
As Theo and Kee leave the scene of a battle between the Fishes and the British Army, a single soldier can be seen wielding a Russian PK machine gun without an ammunition belt or box.
