Does This Ant-Man Easter Egg Explain How Marvel Will Introduce The Fantastic Four?

4. It Wouldn't Be The First Time Marvel's Done It

Back with Iron Man, the MCU was set-up as something a lot more grounded than it is now. There were no portals to deep space or fire-breathing soldiers - everything had an air of believability to it. Of course, when you're dealing with a hero whose biggest villains are a big dragon and an evil mastermind with ten magic rings, that requires some creativity. And so we wound up with the Mandarin's Ten Rings becoming the terrorist group that kidnaps Tony Stark and, much more relevant to Fantastic Four, Fing Fang Foom became a movie character.

In the background of Iron Man's first flight, you can see a poster for a movie featuring a strange dragon-like creature, confirmed to be He Whose Limbs Shatter Mountains and Whose Back Scrapes the Sun (long title, that). Fantastic Four would be a much bigger name to relegate to this sort of reference, but it's very clear Marvel aren't above being a little tricksy with what they bring to the MCU.
