10) Spider-Man Reference (Ant-Man)
Marvel Studios and Sony Pictures made the deal to bring Spider-Man into the Marvel Cinematic Universe when Ant-Man was in the very late stages of production, so while the prospect of there being some sort of Easter Egg or cameo for the wall-crawler was an exciting one, it ultimately seemed rather unlikely.
That’s what made the blink and you’ll miss it mention of a hero who swings through the sky and sticks to walls such an awesome surprise in the final few moments of the movie. This is one of those Easter Eggs which even went over the heads of some comic book readers (it’s a pretty vague description of the character after all), but as these types of thing tend to go, there’s no denying that this was an a real fan pleasing moment and a nice way to announce the long anticipated arrival of Spider-Man into the world of Ant-Man and The Avengers.
