20 Fun Facts About the Iron Man Movies

Without the success of the Iron Man films, the Marvel Cinematic Universe couldn't exist. It's staggering to think about, but there was a time when Marvel wasn't a blockbuster powerhouse. After the big comic collapse of the late '90s, Marvel sold the movie rights to more heroes to keep the lights on.

Enter Iron Man. By the mid-2000s, superhero movies were doing big business. Spider-Man had broken just about every theatrical record at the time for Sony Pictures and the X-Men movies were heavy hitters for Fox. So Marvel wanted in on their own game. So they decided to rally the heroes they had left and do something no one had ever done before: build a shared superhero universe onscreen. Iron Man was the first Marvel Studios movie, the one it was all riding on.

We wanted to take a look back at the series that started it all. Iron Man started the Marvel Cinematic Universe, Iron Man 2 began laying Easter eggs by the dozen, and Iron Man 3 is still the biggest solo superhero film of all time. We decided to dig up some facts about the franchise you may not know. These are the best fun facts and behind the scenes trivia from the Iron Man franchise.
