20 Amazing Marvel Cinematic Universe Cameos You Never Noticed

16. Adam Pally (Iron Man 3)

He wasn't playing a character from the comic books and didn't have any notable ties to any of Iron Man 3's cast members, but Adam Pally's appearance nonetheless resulted in one of the movie's best scenes. Despite having a devoted fan following from Happy Endings, you didn't need to be a fan of that series to enjoy Pally's creepy and borderline deranged Iron Man fanboy who was quick to show off his weird tattoo to a befuddled Tony Stark.
