Continuity mistake: When Baron Wolfgang von Strucker says "We've only scratched the surface and already...", his lips are open. In the next shot, just before he says "there are other facilities doing Hydra's good work around the world", his lips are suddenly closed with no time to do so. This occurs right at the start of the shot and isn't very easy to see, but it is still visible if you look carefully. (02:03:35)
Continuity mistake: Nick Fury's black SUV gets hit by several police cars - the driver's airbag deploys and is visible in all shots until the SUV eventually escapes, at which point the airbag has disappeared.
Continuity mistake: When Captain America takes on the plane outside, the concourse behind him gets shot up and he destroys the plane, which crashes. A little while later the strike team leave the base in convoy along the same concourse that got shot up - there's no damage, and no crashed plane.
Continuity mistake: When Zola's algorithm is deployed and begins acquiring targets, we see a "grid" with the targets chosen. On the right, just above the pictures of the targets, there is a line indicating "targets acquired." Then we see the guns and then a counter indicating the amount of targets acquired, from 210,000 and up, but the next grid we see, in the "targets acquired" line says 133,213 and up. Besides, all the grids have the same pictures, but in different order.
Suggested correction: First, nice work spotting that tiny number. However, the number to which you are referring changes four times (not once as you say), each time, starting from zero. It is not a mistake: If you pay attention to the left side of the UI, there are two widgets, respectively called "Global viewpoint" and "Continental viewpoint." Each time the number starts from zero the, viewpoint changes, meaning that these numbers correspond to each viewpoint. The statistical counter, however, increases cumulatively.
Continuity mistake: On the bridge when the Winter Soldier attacks; when Steve, Natasha, and Sam are in the car stopped, a Hummer rear ends them and starts to push the car. The first shot of the Winter Soldier shows various cars near him. Then a brief shot of Sam, and back to the Winter Soldier and the various cars have changed drastically.
Continuity mistake: When Steve and Natasha visit Sam in his apartment, in one scene, Natasha's hair is wavy. In the very next scene, her hair is pin straight.
Continuity mistake: At one point near the beginning of the infiltration of the helicarriers, Captain America's chinstrap has a twist from his right jaw down to where it covers his chin. This is visible in two shots. The next time his right side is shown afterward, the twist is gone. The chinstrap is too tight for it to have flipped on its own accidentally, and the pad which covers his chin is molded so it wouldn't have sat properly on his face even if it had somehow flipped around. There were undoubtedly several prop helmets made, and this one must have been put together incorrectly.
Continuity mistake: After his last fight with Bucky Steve gets a few wounds on his face, which disappear when he comes out from the water.
Continuity mistake: During the Nick Fury chase scene the amount of bullet holes and the damage change during the whole scene.
Continuity mistake: When Fury and Pierce are talking before the retinal scanner they are beside each other but in the next shot they are several feet apart.
Continuity mistake: When Bucky attacks Cap and the others on the freeway the sun is changing in every shot.
