Continuity mistake: When the message from Göering arrives in the Führerbunker, the signature jumps from one side of the paper to the other. When we first see the machine printing the words "H. Goering, Reichsfeldmarschall", they are on the left side of the paper, as the officer removes the paper from the printer the signature is to the right.
Visible crew/equipment: In the scene where the officers are arguing after their meeting with Hitler you can see a boom microphone towards the top right of the shot. When the men move the boom operators' shadow is visible on the wall to the right of the shot. Taken from the UK Blu-Ray release.
