When the young Australians ride the donkeys past the two British officers under the archway, in the first shot, looking behind the officers, there are three of them. In the next shot, looking to the front of the officers as they ride past, there are suddenly four on donkeys.
The movie opens with young Archy Hamilton running a 100-yard practice sprint at dawn, with his uncle keeping time with a stopwatch. After Archy finishes the race, his uncle shows him the watch and Archy's time is just under 10 seconds (9.58 seconds). If one times Archy's sprint, however, it actually consumes about 15 seconds of screen time.
The Battle of the Nek was not a diversion for the British landing at Suvla, it was a diversion for an attack by New Zealand attack on Sari Bair.
The fourth wave in the attack at The Nek did not start at the the insistence of senior officers. The attack was called off after the third wave, but about half the 150 men in the fourth wave attacked without orders.
In the movie it is stated that a person had to be 21 years old to enlist. According to the Australian War Memorial website for enlistment, in 1914 the age requirements were 18-35 years old, and in 1915 the age requirements were 18-45 years old. However, enlisting below the age of 21 required permission from parents or guardian.
The Australian flags hung against the walls are "up side down" - the union flag should always be in the top left hand corner regardless of being displayed horizontally or vertically. The flags shown at the beginning of the film all have the union flag at the top right.
None of the older officers and non-commissioned officers wear any ribbons on their uniform jackets to denote awards and service in previous wars and battles.
When the ANZAC artillery begins firing on the Turkish trenches just before the climatic battle scene, the guns do not kick back and some have bits of rust around the muzzle edges which indicate that the artillery pieces are not operational weapons at all for they are just popping white smoke out of the muzzles with the camera violently shaking to simulate the guns being fired.
There is a complete absence of bloodstains or bullet holes among the dozens of corpses lying on the ground in the film's climatic battle scene.
During the assaults on the Turkish trenches at Gallipoli many of the Australian army's bayonets are obviously made of rubber - they bend and flap quite noticeably.
While Archy and Frank are plodding across the vast desert, Archy periodically checks their direction of travel using the sun and a pocket watch. When attempting one such check, he tells Frank that he can't take a reading because the sky is overcast. But although there is some cloud cover, it's still bright enough to see the sun for a reading.
At the 1 hour 42 minutes mark, many dead ANZAC soldiers are lying on the ground. One of them, still clutching his rifle in his right hand, visibly moves his right elbow.
The distinctive "Australian accent" actually didn't emerge until after WWI.
In the pub scene when they are about to leave for Gallipoli there are flags on the wall of the Allies - France, Britain, and Australia. There is also a flag of the United States. The battle of Gallipoli occurred in 1915, but the United States did not enter the war until April 6, 1917. It was neutral in 1915, and traded with both the Allied and Central Powers.
