If there is one movie that we all loved this past summer, it was The Dark Knight. But if there was a second movie that I believe we all loved, it was Iron Man. Director Jon Favreau showed off his vision of one of the most exciting and badass comic book characters in history by delivering a fast-paced, intense action experience that had fans’ heart rates going through the roof. And while we all scramble to watch Iron Man over and over on DVD and Blu-ray, it doesn’t hurt to take a look back to the production period — to the concept art. If you thought Iron Man was cool on the big screen, wait until you see where he came from. Have a look at our gigantic gallery of concept art below.
