After watching the newest The Fantastic Four: First Steps trailer, I'm convinced the MCU is giving Mister Fantastic a story Iron Man waited 7 years to get in his movie debut. While there's still several months left until the film releases, the story of The Fantastic Four: First Steps has already started to be fleshed out for audiences via interviews and trailers. The most recent of these - April 17's The Fantastic Four: First Steps trailer - has thus far teased the most plot-wise for what is to come, including addressing the fact Sue Storm is pregnant in the MCU movie.
