Factual error: All SS members have right collar tabs, except Heinrich Müller. His rank at that time was SS-Gruppenführer, same as Otto Hofmann, but his collar tab corresponds to SS-Brigadeführer (one step lower). For addition, the collar tabs of some general ranks changed after April 1942. The conference took place in January 1942, so they have older versions. But as I wrote, Müller and Hofmann were at the same rank, so the tabs should look the same.

Directed by: Frank Pierson
Starring: Kenneth Branagh, Stanley Tucci, Clare Bullus, Simon Markey
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.
Adolf Eichmann: This meeting is not taking place. You will take no calls for anyone at this meeting. Unless the Führer calls. And he won't.
