Goofs

Ballantine and MacChesney are bound and gagged when the last Thuggee is about to behead them after Gunga Din sounds the alarm. Cutter shoots the Thuggee and Ballantine and MacChesney are unbound as they rush to Cutter's side.

Ballantine's bandolier is empty every time it is shown until its last scene, when it's full.

The three are put in the tower as prisoners and locked in. Later when they fool the Guru, they slam the door closed on the Thugees outside the room and lock it from the inside. Prison cell locks are on the outside of the door.

McChesney's bandolier is empty on the ride to the Gold Temple.

The position of the curtain material in Ballantine's belt changes.

During the dance honoring Ballantine's wedding announcement, music is provided by a cylinder phonograph, which was not invented till the late 19th century, and available for sale till the early 20th century (1903) some 20 years after the Thuggee revival uprising in India.

All of the weapons used in the production were US Army issue, from the 1873 trapdoor Springfield seen in dozens of westerns in the hands of cavalry troopers to the more modern M1903 Springfield issued in 1903 and a staple of the US Army till 1942.

When in the village, the command is given to "Form a Square". This type of military formation was used as a defence against large massed assaults, usually of cavalry, and would not have been of much use against riflemen/snipers in buildings. It would have made the troops a larger target.

When the British return to Tantrapur the second time, they posted guards. But when the guards reported, they never called out their post number. They all called out, one at a time, "Post number, all's well".

The knife used to threaten the Guru is a US issue bayonet (1903) not the normal spike bayonet issued to the British troops.

In the end, when Gunga Din's body is being taken away, Colonel Weed does the salute the American way (palm down). The British salute with the palm up. (Sam Jaffe demonstrates it perfectly a few seconds later.)

In the fight atop the fortress, when Cutter is bayoneted in the shoulder, the rubber blade clearly bends.

When the rope bridge drops out from under them, the line of "men" on it all remain upright and stiff as they fall, indicating they are miniatures on a model.

During the rooftop combat at Tantrapur, as the troops run to hide behind a short structure, McChesney's revolver falls from his holster; Victor McLaglen evidently hears it fall, and goes back for it. There's a cut, and then McLaglen is behind the structure with revolver in hand. In some prints, this mistake is minimized and does not show McLaglen going back to retrieve the gun.

During the fighting of the natives (none of whom speak English), a voice can clearly be heard shouting, "Watch out!"

As Tantrapur is being attacked, the click of the Morse sounder bar is heard at the (now vacated) telegraph position, but the bar of the sounder does not move.

Singing and playing music loudly while marching into an ambush might 'boost morale'--but it's tactically arrogant and stupid to alert your enemy early of your approach. The column would have been wiped out, except for Din's last-second warning to go into 'battle formation'.

Instead of using authentic 19th Century British revolvers (Webleys?), the troops carry 20th Century U.S. Colt revolvers.

The breech-loading artillery brought up by the British infantry in the climatic battle are French 75s from World War I.

As the battle at the temple draws to a close, a large carving of an African elephant can be seen.

The rifle that Ballantine carries to the top of the temple is a M1896 Krag-Jorgensen.

In every scene with the snake pit, the strings making them move are visible.

In order to reach the Indian Temple from the military base, Cutter and Din have to cross the perilous rope bridge over a gorge. However, the British relief column is shown marching directly overland from the base to the Temple with no need to cross the rope bridge. Cutter and Din could easily have done the same.
