Best Marvel movie other mistakes of all time
Other mistake: When Tony's house is destroyed by the Mandarin, watch closely when Pepper is blown through the air, just before Tony attaches his suit to her - she's very obviously wearing high-heeled shoes that would make it impossible for her feet/ankles to fit correctly into the suit without them being crunched up by the suit's boots. But later on, when she gets out, if you listen, you can hear the "clicking" of her unbroken heels as she runs around.
Other mistake: Scott Lang is swept out of the tub after having shrunk for the first time. When he lands on the ceramic bathroom floor, falling roughly two feet, there is an audible glass breaking sound and it appears he has broken the flooring with his fall. He then falls through a plaster ceiling to free fall down to a turn table, landing on a plastic vinyl record played by a DJ. The album does not break despite him having fallen from three times the height and landing on a weaker material. Moments later, he is thrown through a second storey window and lands on a car in the street and his weight is now once again sufficient to form a small dent in the hood.
Other mistake: What special "something" does Nick Fury use to pick the Cosmic Cube up at the beginning of the movie? All I saw was that he had on a glove, but in Captain America it was said only people with special abilities could handle it, and even later in the The Avengers when Banner is moving the cube, he uses a gadget and he's the Hulk! Did I miss something?
