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. (00:13:30)
Continuity mistake: 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 mistake: 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. (00:20:00)
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. (01:58:15)
Continuity mistake: Part 3: Stoller's cigar is longer in full shots than it is in close-ups. (00:42:30)
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 1: During the Siena Italian festival in what is supposed to be 1939, you can see in several shots that the crowd is wearing 1980s clothing (including tank tops, shorts and modern athletic shoes).
Factual error: Several times throughout the miniseries, parts of London are shown with the flags of various allied nations flying from buildings. These include the Canadian maple leaf - which wasn't adopted until 1965.
Visible crew/equipment: Part 1: The microphone shadow follows Natalie and Byron when she comes to see him, both in his room and out in the hall. (01:38:50)
Visible crew/equipment: Part 4: When Eleanor Roosevelt walks in on the meeting between Captain Henry and the President, the boom shadow is moving on the wall above the door. (00:03:30)
Factual error: One of the medals on Pug Henry's uniform throughout the series is a Bronze Star. Winds of War is set in 1939-1941. The Bronze Star medal wasn't created until 1944.
Continuity mistake: Part 4: When Captain Henry dines with Pam, a bottle of wine appears from nowhere on their table between takes. A few shots later, though no waiter has approached them and neither of them has touched the bottle, the glasses are filled with wine. (00:51:40)
Continuity mistake: Part 6: When Pug Henry is conversing with Palmer over drinks, Pug holds his glass in one hand. When the shot cuts, he's holding it with both hands. When it cuts again, he's back to the one-handed pose. (01:30:20)
Factual error: The USS Arizona Memorial can be seen during the first bombing scene of Pearl Harbor in the dark smoke.
Factual error: The batman at the RAF station introduces himself as "Aircraftsman Horton" (which also appears on the credits). While a common mistake made by those outside the RAF, the rank is actually Aircraftman, without an "s".
Factual error: When Pug first arrives in London, a car can be seen driving on the right.
Visible crew/equipment: Part 4: The boom's shadow puts in an appearance on the wall behind Captain Henry and Churchill. It's moving just under the painting hanging in the background. (00:49:00)
Factual error: Part 6: As Roosevelt is getting onto the train, the superimposed title identifies his location as "Silver Springs, Maryland." But he's in Silver Spring (no S), not Silver Springs.
Continuity mistake: Part 7: Aaron and Natalie walk into the Coliseum arm in arm. But when the camera angle reverses, they're suddenly standing several inches from each other. (01:11:10)
Factual error: Alfred Jodl is listed in the credits as a Field Marshal. He actually held the rank of Colonel-General.
