Continuity mistake: In a head-on shot, where Adolf Eichmann is the main character in the shot, he is shown lighting a cigarette, fully, and lowering his lighter. In the very next shot, he is shown from a side angle as a background character and again has the lighter to his cigarette, and lowers it, although it had already been lit in the previous shot.
Continuity mistake: Dr. Kritzinger can be seen standing looking out a window while the rest of the cast is sitting at the table, applauding something said by Kenneth Branagh. The camera angle then changes, the applause is still going on, and you can see David Threlfall suddenly sitting at the table. (00:26:25)Phillip Anderson
