If you look at Iron Man's first suit, the Mark 1, and compare it to the hero's nanotech suit from "Avengers: Infinity War" and "Avengers: Endgame," a lot has changed, but it's not just the technology in the world of the Marvel Cinematic Universe. Animation tech has also evolved in the real world to make this suit possible on the big screen. We spoke with some of the VFX artists who worked on Iron Man’s suit over the past 11 years including Industrial Light & Magic, Weta Digital, Cinesite/Trixter, The Embassy, and Framestore to find out what challenges they faced along the way and how they were able to make the suit look so real.
