Factual error: When the action moves to England after the failed award ceremony, the British Union Flag hanging from the wall is upside down. The broad white band should be at the top left (nearest the top of the flag pole).
Factual error: In the section during the movie reel, there is footage of the 1939 world's fair in New York. The Unisphere is shown. Unfortunately, the Unisphere was constructed in 1964 for the 1964-1965 world's fair. The Perisphere (and Trylon) were the centerpiece of the 1939 fair. The Perisphere was a sphere 200 feet in diameter. The Unisphere is still standing in flushing meadows park in New York city.
Continuity mistake: After Steve throws Heinz Kruger, the assassin sent to kill him, out of his boat, both Steve and Heinz are bone dry despite being fully submerged in water only moments before.
Revealing mistake: When we see the new recruits at boot camp, they are wearing M1 Helmets. But if you look closely, they have rivets through the sides of each helmet where the chinstrap bales would be. In reality, the M1 helmet chinstrap bales were and continued to be welded onto the shell of the helmet. This indicates the helmets in the film are probably plastic replicas with the bales being riveted in place.
Continuity mistake: During the chase scene involving Rogers and the Hydra spy that happened after Rogers got his new powers, the windshield of the cab the agent was driving was shot twice. In some shots, especially once Rogers landed on the roof of the cab, the windshield has no holes.
Deliberate mistake: In the scene where they break into the train from its roof, you can notice that despite the high speed and the consistent wind, Captain America's fellows have no difficulties in running, standing up still, and even jumping, like they felt no air resistance. Moreover, you can see that their hair is not moving at all, completely missing to realize any "windy" effect.
Factual error: In the closing credits, during the montage of World War II posters, the American flag appears wrapped around a cannon barrel. The flag has 50 stars, not the then-correct 48.
Factual error: At one point the Colonel references "MI-6" which is the current British term for their intelligence service. However this terminology didn't exist until after the war. During WWII it would have been referred to as Special Operations Executive or SOE.
Factual error: The German Stielgranaten - as well as other traditional German WW II hand grenades - did not have a ring and pin like the ones the Allies used, but had a string which had to be pulled hard in order to arm them. Thus they wouldn't make such a distinct 'ping' as they do in the movie.
Continuity mistake: When Captain America is ready to jump out the plane, he is looking at Peggy Carter when he reaches for his goggles, the angle changes to the outside and Cap is seen with one hand out the plane and the other in, with his goggles up. it switches back inside and his goggles are on.
Factual error: Oddly for a movie set in the 1940's when nearly half the U.S. population smoked, absolutely no one in the movie is seen smoking. More recognizable in the bar scenes, almost everyone in that bar would have been smoking.
Continuity mistake: At the end of the chase through New York, when Steve picks up the taxicab door and uses it as a shield, he has a wet spot or stain on his right knee. Moments later it is gone.
Continuity mistake: The windscreen on the flying wing appears to be completely intact when it is discovered in the present. Not only is it implausible to believe it survived a head-on crash without being damaged, but also during the final fight on board, it receives several bullet holes.
Factual error: The early scene in the movie theatre is in 1943. In the opening newsreel a Sherman Firefly tank is shown. This tank was not made until early 1944 [the long barrel and spherical muzzle brake are distinctive]. Even if we were to assume the tank was made earlier in the Marvel Cinematic Universe due to people like Stark working for the Allies it still would not be shown in a newsreel anyway for security reasons, with German spies and sympathizers present in the US during the war. (00:09:30)
Continuity mistake: During the final battle on board the 'flying wing' between Captain America and Red Skull, the finish on CA's shield appears damaged and scorched. Yet in the opening sequence of the movie when his shield is discovered under ice inside the frozen 'flying wing' it appears undamaged.
Factual error: In one scene, Steve Rogers is wearing a Combat Infantry Badge (CIB) on his pocket flap, below his ribbons, with his jump wings above the ribbons. Proper wearing would be CIB on top, jump wings, then the ribbons, all above the pocket flap.
Character mistake: Dr. Erskine says he lives in Queens at 73rd Street and Utopia Parkway. Actually, 73rd Street is well to the west of Utopia Parkway (both run north-south). Erskine must have meant 73rd Avenue, which does cross Utopia Parkway.
Continuity mistake: When Rogers and Agent Carter are about to enter the antique shop for the first time, one shot shows Rogers raising both arms to place his cap on his head. The shot changes and Rogers' hands are now down, and he begins to raise them again.
Factual error: In the scene at the World Expo, the flags are being displayed. Next to the US flag is the Bahamian flag. The Bahamas didn't have a flag until 1973 when it gained its independence. It used the British Flag or the "Union Jack" since it was still a part of Britain. Also, the flag disappears a few seconds later.
Other mistake: When Schmidt sets the self-destruct timer at the Hydra base, the clocks count down at twice the speed of real-time.
Chosen answer: A couple of techniques were used. In most cases, Evans would film the scene normally, then the effects team would digitally shrink his character down to the smaller size. This would generally require some on-set adjustment to allow for eyelines - in some cases Evans would be physically lower than other actors, in others, they would look at his upper chest while he looked over their heads. In a few cases, actor Leander Deeny, who possessed the necessary scrawny physique, would film the scene, collaborating closely with Evans to ensure that the character's mannerisms remained the same. Deeny's features would then be digitally replaced with those of Chris Evans. Deeny appears briefly in the movie as the bartender in the pub Rogers visits to recruit his team.
