7. The Fake F-35B (The Avengers)
From a continuity error to a factual one, and one of many Im afraid. In fact, despite being the biggest Marvel movie to date, Joss Whedons The Avengers is strewn with errors, with around 70 mistakes being pointed out by keen-eyed fans. As has been the case with most MCU movies, The Avengers was guilty of taking liberties with the machinery and weaponry they chose to use, with mistakes which were present in the concept art (shown above) still making it to the screen. During the scene in which Bruce Banner Hulks out and jumps onto the F-35B hovering ominously close by, we watch on as the aircrafts two guns open fire on him. In truth, the F-35B only has one gun, and that is actually mounted externally to the underside of the fuselage. It would not be possible for guns to be mounted inside an aircraft like they are in the movie.
