Pifias

Jeeps from WW2 were all manual transmission with a long gearshift lever. Tulley is seen driving a Jeep more than once after he has his right arm broken. That would have been impossible to do.

In two shots you see a double-deck bus. While these existed in Berlin at the time, this one is a London bus as the entry/exit platform is on the left rather than the right.

The newsreel speaker says the Potsdam conference takes place in "Emperor William's former palace". This is not correct. The Cecilienhof palace was built for the last crown prince of Germany, who lived there from 1917-19 and from 1926-45.

Colonel Muller says "a year ago I was up to my balls in mud at Anzio" The Anzio operation was over by May 12, 1944. The European part of the war ended May 8, 1945. It would have been a lot more then a year since he was fighting in Anzio.

Tully wears a hat with a silver border trim. This is an officer's hat, but Tully is clearly enlisted.

When Tully is leaving Sikorsky's office, he is supposed to have a broken right arm. Yet, when he rises from the chair, you can see him push off the arm with his right arm (both arms, actually) and then open the door with his right hand.

When Sikorsky checks the money, there are banknotes in the bundle with the same numbers. Tully is also a counterfeiter? :)

Sikorsky examines some currency, paying close attention to the serial numbers. He's shown examining the bills: their serial numbers are rendered in an OCR (Optical Character Recognition) typeface, which wouldn't be introduced until decades later the period of this film.

Camera shadow on the prosecutors' uniform at 57:59 into the film.

Upon Geismer's first visit to her apartment, Lena lights the stove and begins heating a kettle. Shortly, she announces she is going to bed, leaving the kettle over the stove's flame (as well as a lit candle on the table).
