Revealing mistake: When Tom Cruise and Bill Nighy go to see Tom Wilkinson for the first time there are 2 reverse shots from behind Tom and Bill - if you look you can see Tom's hand is still there - it has been digitally removed in all other shots.
Valkyrie (2008)
1 revealing mistake
Directed by: Bryan Singer
Starring: Tom Cruise, Bill Nighy, Kenneth Branagh, Tom Wilkinson, Terence Stamp, Carice van Houten
Factual error: Approximately three quarters of the way in to the film, there is a close up of a German soldier handing an officer a file of documents. The helmet that the soldier is wearing is a post war 1960s version. This can be determined by the lack of an air vent and rivet on the side of the helmet.
Henning von Tresckow: We have to show the world that not all of us are like him. Otherwise, this will always be Hitler's Germany.

Question: Why did all of the officers and high-ranking officials put out their cigarettes when Hitler's plane landed at the airfield?
Answer: They are supposed to stand at attention when he arrives and salute when he walks past them. It is considered bad form to salute the Führer (or any leader) with a cigarette in your mouth or hand.
Answer: Hitler was fanatically anti-tobacco: https://www.theatlantic.com/health/archive/2014/07/the-nazis-forgotten-anti-smoking-campaign/373766/.
