During the German counterattack, Easy blows up a machine gun nest in a building marked "petite restaurant" with a bazooka, collapsing the wall. Later, in the shot that eventually shows Bull hiding in the culvert, we see the Germans maneuvering past the same building, now undamaged. This could not have been the opposite side of the building since it would mean the Germans had their backs to the retreating Americans.
The allied forces throw a rocket at the Dutch restaurant, leaving a huge hole in it. Still, they are forced to retreat. Afterwards, we see the victorious Germans in front of the restaurant with no sign of the previous damage.
At the 37 minute mark, Roy Cobb is squatting down, firing his Thompson over a short wall. The wall is hit by a shell and breaks apart as Cobb is firing a burst. The camera then immediately cuts to Cobb, who is now seated with his close to his chest.
Les Hashey sees a medic shot by a German in the left leg. When we next see the medic he is holding his right leg and bleeding from it badly, and his left leg is in fine shape.
While retreating after the battle in Holland Lt. Nixon is struck in the helmet by a sniper's bullet, when in the actual war this occurred while the company was crossing a field and a machine gun opened fire. Nixon survived as portrayed in the movie.
A Tiger tank (actually a T34 mocked up to look like a Tiger) participates in the fight. But Tigers never fought in Nuenen. It is probably a stand in for a Panther; the 107th Panzer brigade fighting in Nuenen had a considerable number of them.
One of the vehicles in the Nuenen fight is a Jagdpanther. Whilst these vehicles were involved in the fighting related to Market Garden, they served more to the west; the 107th Panzer Brigade, fighting in Nuenen, did not have them. It should have been a Jagdpanzer IV.
At 11:08 In the overall scene just after characters receive their briefing for Operation Market Garden, two P-51Ds fly over the bivouac site then bank left. But ailerons on the Mustangs (control surfaces on the main wings of the airplanes) are deflected the opposite direction. In this configuration the two Mustangs would bank right, not left.
Buck Compton and Babe Heffron are playing a game of darts. To finish, Babe says he needs "double seven". He throws and apparently wins the game, but the arrow hits "treble seven", instead of double, indicating that he didn't win (yet).
(at around 16:30) In the scene where the paratroopers are landing in Holland you see a paratrooper land and roll. Immediately after, Sgt. Denver 'Bull' Randleman runs in from the left and helps a paratrooper out of his chute, telling the trooper "Don't be sorry". During this scene, the shadow of a parachute in the background never moves or changes until the camera pans all the way to the right, when the cables release and the obviously suspended parachute and actor roll into the shot, simulating the landing.
When Easy Company are parachuted into Holland, just after we see Pvt Hashey struggling with his harness, a paratrooper lands and rolls in the center of the screen. His parachute drops in a heap behind him, clearly indicating that he and his 'chute have been dropped from a platform, gantry or crane.
Near the end of the sequence where the 101st drops into Holland, a paratrooper can be seen hitting the ground who is completely computer generated.
Private Miller is chastised by Cobb for wearing a "presidential unit citation" even though the replacement soldier did not fight in Normandy to earn the award. This citation was not called the "presidential" citation until 1966, when the award was initiated in the 1940's it was called the "Distinguished Unit Citation".
As the paratroopers make their way into the town of Nuenen, they take cover near a church. The windows of the building they hide behind have modern plastic frames.
(at around 33 mins) When Bull is crawling away from the burning tank, on shot of the rear of the tank reveals two crew members in white (one wearing a baseball cap) walking alongside to the right of the tank.
When Sgt. Randleman crawls away from the damaged US tank which is chasing him, when the tank is seen from behind, two crew members are visible walking along the right side of the tank, partly hidden by some bushes.
The airborne ("Market') phase of Operation Market-Garden focused on capturing a series of bridges over which the British 'Garden' armored ground offensive could pass. The 101st Airborne division was supposed to capture the bridges in the Eindhoven area. (The 506th Regiment was specifically tasked to take the bridge at Zon.) However, in their briefing for the operation, neither Richard Winters nor Lewis Nixon say anything about taking and/or holding bridges.
When Pvt. David Kenyon Webster spots the road sign for Nuenen, he states: "Vincent Van Gogh was born in Nuenen!". Van Gogh was born in Zundert, although he did live in Nuenen for two years from 1883-1885.
When pulling out of Nuenen, SSgt. Guarnere queries SSgt. Martin about Randleman's whereabouts. However, he uses the title 'Major', when in fact, Randleman is only a Sergeant.
