Trivia: Sam Rockwell said he received a call from Jon Favreau about playing Tony Stark in the first film, but never heard anything more about it. He ended up getting the part of Justin Hammer in this film through his friendship with screenwriter Justin Theroux.
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.
Chosen answer: Hammer is impatient. he did not want to waste time and money to go find Vanko's bird. he just wanted Vanko to get the work done.
