Trivia: At the end of the movie when Nick Fury and Tony Stark are talking in the warehouse, the news report seen on the TV is a broadcast from the fight between the Hulk and the army at the university campus from 'The Incredible Hulk' movie.
Trivia: During the movie, S.H.I.E.L.D. agent Phil Coulson holds up a circular red, white and blue object with a star and asks where he got it. That was Captain America's shield, which also appeared in the first movie in the background, which caused a stir by the fans.
Trivia: Spoiler: The film closely resembles several key Iron Man stories from the comics. The part when he was drunk references the "Demon in a bottle" storyline, where Rhodey dons an Iron Man suit. The part of him dying is somewhat similar to "Ultimate Iron Man." Also, the idea that his technology is used in a way he doesn't like and having a battle is similar to the "Armor Wars" plot.
Trivia: Ivan Vanko is a mixture of two Iron Man villians: Whiplash, which is the primary part, and Crimson Dynamo. Anton Vanko (Ivan's father) was the original Dynamo and in the final battle, Vanko wears a suit similar to Dynamo, as it's a hybrid between that and Whiplash.
Trivia: Attack of the Show host Olivia Munn mentioned she was to have another role in the movie. She played reporter Chess Roberts, but originally had a somewhat bigger role. She was to play a girl at Stark's birthday party who then appears in his bedroom. The scene was eventually cut because it didn't have any comedy in it.
Trivia: During the fight between Tony and Jim, Tony says "Step up if you think you have what it takes to be a war machine". War Machine is the name of the modified Iron Man armor that Jim wears in the comics.
Trivia: As with the last Iron Man movie stay till after the end credits for an extra character spot.
New this month Trivia: When Tony is flipping through his father's notebooks, he comes across a sketch of an object that looks like a cube within a cube with lines connecting the corners. This object is called a tesseract, which is a three-dimensional model of a four-dimensional object. Or in this case, a two-dimensional drawing of a three-dimensional model of a four-dimensional object. This is a foreshadowing of The Tesseract, one of the Infinity Stones, which plays a huge part in several of the other Marvel movies.
