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.
Trivia: In the scene at the start of the film where Lt. Bromhead is riding his horse along and across the stream, it is not Michael Caine on the horse, as at that stage in his career he could not ride, he told the director he could as to get the part. Caine did try to ride it but he could not do it, so one of the filming crew took his place as a riding double. That's why the camera pans down onto the horse as it crosses the stream.
