At the end of the film Speer is told that Adolf Hitler died at 1500 or 3:00 PM. This is wrong. The approximate time of Adolf Hitler's death is 4:30 PM.
Fritz Todt is shown wearing a Luftwaffe colonel's uniform the night before his fatal plane crash in 1942. This is an error. At the beginning of the war he was appointed a Major General in the Luftwaffe on the basis of his service as a pilot in WWI. He would either have worn this rank or, more likely, his organization's own uniform.
