Iron Man (2008)
In case you have never noticed, the Marvel Cinematic Universe loves to connect all of its movies through references through the movie, both big and small. In fact, it’s always been a part of the universe! Iron Man, the first film in the franchise, started it all back in 2008.
In one scene, while Tony Stark dons his iconic Iron Man outfit, some eagle-eyed fans spotted something rather hilarious that everyone else needed a pause button to notice. Behind Stark, on a table, is none other than Capitan America’s shield, sitting, taken apart. It wasn’t until three years after Iron Man release that Capitan America: The First Avenger hit the screens! They always had a plan in mind!
