The Iron Giant is a 1999 animated science fiction film directed by Brad Bird with the voice talents of Eli Marienthal, Vin Diesel, Jennifer Aniston, Harry Connick Jr., Christopher McDonald and John Mahoney. Adapted from the novel The Iron Man by English writer Ted Hughes, the film was a disappointment at the box office despite favorable reviews. However, the film has gone on to become a cult hit and opened doors for director Bird, who went on to direct such animated features as The Incredibles and Ratatouille as well as the 2011 live-action film Mission: Impossible - Ghost Protocol.
The following weapons were used in the film The Iron Giant:
General Rogard carries an M1911A1 and it's mostly seen in his holster as well as when he uses it to shoot at the Iron Giant. FUN TRIVIA FACT: In this scene, and in the other scenes where General Rogard fires his M1911A1 at the Giant, the pistol sound effects are the EXACT same sound effects used in Terminator 2: Judgment Day for the Beretta and Browning pistols in that film.
Rifles
M1 Garand
An M1 Garand is seen used by a soldier when Rogard's jeep stops after the Iron Giant approaches town from the forest while destroying tanks. All M1's in the film appear to be fitted with M7 rifle grenade launchers.
M1 Carbine
A U.S. soldier was armed with a M1 Carbine during the first attack on the Iron Giant.
Winchester Model 70
Winchester Model 70 rifles were used by the two hunters when they killed a deer before Hogarth and the Iron Giant found them. The hunters drop their rifles and flee at the sight of the Iron Giant.
Daisy Red Ryder
A BB Gun was used by Hogarth Hughes in the beginning of the film while searching for the Iron Giant at the power station. It seems to be a lever-action weapon, possibly a Daisy Red Ryder. Hogarth originally tapes a flashlight to the barrel, but the flashlight disappears when the Iron Giant crushes the weapon underfoot while following Hogarth.
Machine Guns
Browning M2HB Heavy Machine Gun
Near the end of the film, U.S. Army vehicles (primarily M41 Walker Bulldog tanks) can be seen fitted with Browning M2HB heavy machine guns when attacking the Iron Giant (voiced by Vin Diesel), mistakenly believing he was attacking the town of Rockwell.
Browning M3 Heavy Machine Gun
In addition to the Army, the U.S. Air Force also becomes involved in the attack against the Iron Giant, sending F-86 Sabre fighter jets to try to destroy him, using missiles and built-in Browning M3 heavy machine guns to eventually shoot him down, but not destroy him.
Browning M1919 Machine Gun
Army jeeps are fitted with a Browning M1919 machine guns.
Launchers
M20 "Super Bazooka"
The first weapon fired at the Iron Giant by the Army, several soldiers can be seen armed with M20 "Super Bazooka" rocket launchers.
