20 Things You Didn’t Know About Iron Man 2
9. Peter Parker Has A Retroactive Cameo In The Movie
Shortly before the release of Spider-Man: Homecoming, Peter Parker actor Tom Holland made the jaw-dropping revelation that Parker actually made his first appearance in the MCU years before Captain America: Civil War.
In fact, he briefly showed up in Iron Man 2 as the young boy at the Stark Expo wearing an Iron Man mask who is saved from the Hammer drones by Iron Man.
Given that we never see the boy's face and the Expo takes place in Queens, it fits pretty neatly, even if was ultimately contrived after-the-fact rather than a deliberate set-up by Marvel Studios bigwig Kevin Feige or Jon Favreau.
Though you can argue that Holland himself isn't really in a place of creative authority to "confirm" this, it was later approved by Feige himself, so it's basically canon now.
