Continuity mistake: When Corporal Allen pulls Private Hitch off the ramparts when Hitch is shooting at Zulu's in the hills with his pith helmet on backwards, Hitch gets shot in the leg, and Allen pulls him in. Allen is shot in the chest, he clutches his chest, falls inside ramparts with blood underneath his clutching hand. When you see him after camera cut he is clutching the OTHER side of his chest.
Continuity mistake: After the Zulus' final charge which follows the rendition of "Men of Harlech", they appear on the hills round Rorke's Drift to give their salute to the garrison before leaving. In one shot, filmed from behind the Zulus, both buildings, church and hospital are standing even though the hospital burned down during the battle. Seconds later in the next shot of the post from the hills, only the church is standing and a column of smoke rises from the ruins of the hospital. I believe that some scenes were filmed of the Zulu Impi crossing the Buffalo River and marching to Rorke's Drift, but were cut from the film. The first shot mentioned above could be one of these.
Continuity mistake: When Bromhead is standing on the burning roof firing his pistol at the Zulus running about below, you can see there's no gun smoke or muzzle flash from the barrel. It looks as if he's just pointing it around.
Continuity mistake: During the lull before the attack on the hospital, when Pte. Hook walks over to the doorway to speak to somebody, his suspenders are dangling down from his waist. A minute later, when the camera angle changes, his suspenders are suddenly up over his shoulders. Then, when the camera angle changes again, his suspenders are back down again.
Continuity mistake: During one of the first Zulu attacks, a local is walking behind Chard carrying a box of ammo with a bayonetless rifle slung over his shoulder. The man is hit by a bullet and goes down. Chard quickly checks the man and then realises he's being charged by three Zulus. He shoots the first with his pistol, runs out of ammo so makes a grab for the dead mans rifle which now suddenly has a bayonet attached to it.
Continuity mistake: During the battle in the hospital, when Hook bayonets a Zulu up against the wall, the bayonet clearly goes under the armpit, not through as the mark left on the wall afterwards would suggest.
Continuity mistake: One shot of the Zulus attacking is shown in reverse - all the Zulus appear to be left handed.
Continuity mistake: Colour Sergeant Bourne goes one on one with a large Zulu warrior and kills him. Later, this same Zulu warrior is alive & well.
Continuity mistake: Chard gets struck on the neck by a Zulu shield, and he falls as if severely wounded. There's no blood on his neck, yet later when Bromhead pulls him upright, his collar is smeared with it. Anyway, how can a blow like that knock him silly? Bromhead was later struck by a Zulu shield on the neck as well, yet he was fine.
Continuity mistake: During one of the attacks, the Zulus are charging en masse towards the ramparts manned by British riflemen. When Bromhead yells "Fire!" the soldiers open fire with their rifles....and some Zulus at the REAR of the charge fall dead whilst those in the front continue charging, uninjured.
Continuity mistake: During the latter Zulu attacks, a number of charging Zulus fall to the ground clutching their chests as if shot before a single shot has been fired.
