Okay, anyone who has seen Robert Downey Jr.'s Tony Stark knows that Downey likes to ad-lib a lot, like randomly offering Captain America a blueberry during The Avengers.

However, Kevin Feige recently revealed an improvised line that helped set the tone of the Marvel Cinematic Universe as a whole, way back in Iron Man.

Now, the movie ended with a press conference, for those who haven't seen it, where Tony Stark was told to just read what was on his cue cards, and say that Iron Man was just a bodyguard, AKA the story that Tony Stark told for a very long time in the comic books. But instead, Tony Stark said, "The truth is...I am Iron Man."

Apparently, this was something that Downey Jr. came up with. It was completely unplanned. It would change the planned tone of the Marvel Cinematic Universe to something different from the comic books if they went with it. But because it was something that was completely in character for Tony Stark, they decided to go with it.

And, obviously, people loved it!
