Factual error: When Pug comes home, Rhoda puts on a Christmas record. The record player has an automatic changer that drops the disc and then moves the arm into place. Though a small 45 rpm changer was designed as early as 1938, and this movie's set in 1942, the type Rhoda uses here wasn't around for another 20 years. (00:09:00)
Factual error: Part 10: Near the end, the superimposed title identifies the battleship on screen as the U.S.S. Iowa. But the visible hull number is 62 - which was the New Jersey, not the Iowa. The U.S.S. Iowa's hull number was BB 61. (01:07:00)
Factual error: Part 3: Byron drives his mom through Hollywood, passing the landmark "Hollywood" sign on the hillside. But in 1942, that sign would still have its original configuration, which read "Hollywoodland." It wasn't truncated until 1949. (01:32:30)
Factual error: Part 10: The naval flag flying aboard the U.S.S. Iowa has 50 stars. It should have 48.
Factual error: When Byron goes to Paris in search of his son, he is in the uniform of a lieutenant commander in the US Navy, however he has "scrambled eggs" on his cover, reserved only for full commanders and above.
Factual error: During Himler's visit to Auchwitz, the VIPs travel in a motorcade. The cars have their steering wheels on the right side of the cars, meaning they come from a left hand traffic country. Definitely not German. (01:41:27)
