Trivia: In the final scene of the film, as Tony is unfolding the blueprints for the new Stark Tower, if you look very carefully (slo-mo may be necessary) you can see files with a symbol representing each Avenger in the upper right corner of each file - Captain America's shield, Thor's hammer, etc. The implication being that Tony will build a section of Stark Tower for each of his friends.Brad
Trivia: For the post-credit scene where the group are eating schwarma together, Chris Evans had to wear a prosthetic jaw because he had grown a beard for another movie and couldn't shave it off. It's also why he's resting his head on his hand through the entire scene, conveniently covering up most of his face.
Trivia: Paul Bettany, who voices Jarvis in this and the standalone Iron Man films, hasn't seen any of them. In an interview he said "This is robbery. I walk in, I say some lines on a piece of paper for two hours, and then they give me a bag of money and I leave and I go about my day...I've never seen one of them...It's not because of any snobbishness, it's just not my thing."Jon Sandys
Trivia: Stan Lee had two cameos in the movie but his first appearance was cut. In the scene when Steve Rogers is at the cafe seen in the final fight where he first encounters the waitress who had become infatuated with Captain America after he saves her. Stan Lee basically calls Steve a moron for not asking for her phone number.SheWhoLovesMovies
Trivia: The first movie to ever gross over $200 million domestically in its opening weekend. (And somewhat coincidentally, it was released almost exactly ten years to the day after "Spider-Man" - the first movie to gross over $100 million in its opening weekend, and also based on a Marvel property).TedStixon
