It's pretty safe to say the entire world is obsessed with iMarvel movies — the numbers don't lie. When a film about a bunch of unknown superheroes, adapted from a relatively basic comic book like iGuardians of the Galaxy, can push over the billion-dollar mark, you know Marvel is onto something good. When the firsti Iron Man came out, no one really thought it was going to flourish as it did. However, through great filmmaking and Robert Downey Jr.'s charisma, Marvel managed to spin a 10-year web of unparalleled success, creating rabid fans in the process. The real question now is, are you one of those rabid fans? Sure, maybe you've seen all the movies, but have you really watched them? Have you taken note of the little intricacies of the plots and the relationships of the characters? We would bet you can't get every single question right on this MCU quiz. Take the test, get your score, then compare your results with your friends. Avengers fans: assemble!
