Revealing mistake: When Natalie Portman's character is about to be executed, if you look at the wall behind the executioner, you can see a modern metal drainpipe.
Other mistake: The Sydney harbor scenes have the backdrop of the opera house. The buildings (aka "The Toaster") beside the opera house were not completed until 1998. The film was set in 1976-77.
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.
Factual error: In a scene that is twenty-eight minutes into the movie, one of the characters is seen running up to check out a new Cadillac that had been given to him by the owner of Chess Records. A 'super' appears at the bottom of the screen which reads "1952" in order to set the chronological time. Only problem is, the Cadillac is a 1956 model. Any old car buff, particularly one like myself who writes a weekly column for the St. Louis Post-Dispatch, would know in a heartbeat that this car was four years ahead of the year indicated on the screen.

Factual error: When Einstein is crossing a bridge on his way to the university, two German flags (black-red-gold) are flanking the bridge. The scene is set in 1914, so it should instead be the 'German Reichsflagge' which is black-white-red. Only after WW I, in August 1919, was the black-red-golden flag officially used to represent Germany. (00:38:50)
Factual error: There is a running camera shot at the UN of national flags, the current Canadian flag is displayed but it was first introduced in 1965, the movie scene is suppose to take place in 1964.
Continuity mistake: At the beginning of the film when Georgiana is talking with her mother about her engagement, the curl running down the back of Georgiana's neck disappears and reappears multiple times.
Audio problem: The day after Operation Mardonius, when the first set of bombs explodes you first see the explosion and then hear it after a second, then as the last bombs explode you both see and hear the sound at the same time.
Factual error: The SS Officer is repeatedly addressed as "Herr Oberst". This is a Wehrmacht rank designation, and could possibly have been correct for them addressing an SS officer, but fellow SS officers would have used the correct term "Standartenführer" (without the "Herr"). On one occasion the lower rank SS officer is address as "Herr Leutnant" which is equally wrong, should be "(Ober)sturmführer"
