Being an on "old school" Iron Man fan - I have copies of the Tales of Suspense Issues where Iron Man first appeared- I was curious how they play him on the screen. The screen apdaptation makes Stark more callous and a bigger playboy, but plays well into his transformation to Iron Man. The movie version also takes some liberties with other characters - again they work well for the big screen. Although Jarvis being changed into a computer program seemed to being taking it a little too far. However, it does give the charater some new abilities that a human butler would not have. Overall, an good update that even this "old school" Iron Man enjoyed.
