Continuity: Part 7: The car Captain Henry parks near the cliff at the very end moves itself between takes. It's sitting on the road when he parks it, but when we cut to an overhead shot after he gets out, the car has suddenly moved off the road and into the dirt alongside it.

Continuity: Part 3: Hitler enters the study and stands near the door with his hands clasped behind his back. The angle reverses, and his hands move instantly to his sides. Reverse again, and he's returned to his original stance.

Factual error: Part 4: The cord on the telephone Pug uses to call Pam should be a straight wire. Instead, it's coiled: a design not yet in use in the 1940s.

Factual error: In the final scene of the mini-series, Captain Henry stands on a cliff next to his car, looking down at Pearl Harbor. But Pearl Harbor is surrounded by entirely flat terrain. There are no cliffs.

Factual error: Part 6: It's 1941, and Pug and Stimson are in a small boat crossing between ships in the fleet. The USS Missouri, with its BB-63 hull number plainly visible, passes behind them. The Missouri wasn't commissioned until 1944.
