When Marvel Studios launched Iron Man in 2008, few people thought the movie would work. After all, Iron Man wasn't Marvel's strongest or favorite character, so the movie was something of a gamble. Of course, it all worked out, and Iron Man became a far more appreciated character on and off the screen. Tony Stark and Iron Man were introduced in Tales of Suspense #39 back in 1963, so the character has been around for more than half a century.
In all that time, through the comic books, movies, graphic novels, video games, and other media, the character has developed into a significant one in the Marvel Universe. Despite so much history, or perhaps because of it, there are a ton of things you probably didn't know about Iron Man.
