Best Marvel movie character mistakes of all time
Character mistake: When Steve and Romanoff "switch on" Arnim Zola, Zola says "I may not be the man I was when the Captain took me prisoner in 1945." In the first Captain America, it was shown Steve took Zola into custody the same day as his friend Bucky supposedly died. However, the bio of Bucky shown at the Smithsonian earlier in the film said that he died in 1944.
Character mistake: There is a misspelling on the cover of the issue of Forbes magazine shown in the presentation about Stark's life. It reads "Tony Stark takes reigns at 21". The correct spelling of the word is "reins". Stark may "reign" at Stark Industries but he would take over the "reins" of the company.
Character mistake: When Happy is in hospital, two bad things happen: One, when a nurse comes into the room, she injects a drug into his IV line, but she doesn't kink the line above where she is injecting, so the drug goes both down and up the line. Two, Happy's IV line isn't attached to a pump. The nurse manually fiddles with the flow rate of Happy's IV. But the fiddling leads to nowhere, as she doesn't look at the chamber where the drops come out - this is very important, as the IV bag can run out anywhere from 30 mins to 3 hours.
