(at around 1 min) The Waffen-SS officer at the beginning of the movie has no rank or SS Rune collar tabs on his tunic, and he's wearing a Private's greatcoat with privates shoulder straps.
(at around 41 mins) In the nighttime village scene where the native woman is giving birth. The hut is lit from the left by an pure white light source, so strong that it shines through the gaps in the straw structure. There are plenty of campfires to light the scene, and certainly no place for a pure white light source that strong in this location.
The uniforms worn by the British major and the other Imperial troops are from the wrong period. They are uniforms that were worn up until the Second World War, and NOT after, as shown in the movie.
In the scene where the flag is being taken down and folded, "Taps" plays in the background. "Taps" is an American military song, and is not played by the British Army. "Last Post" would have been the appropriate music.
