Revealing mistake: Some of the shots involving the terrorists firing at the prototype suit are "flipped" duplicates of other shots. In the scene where he first emerges from the cave, several of the terrorists are firing M4-type rifles with the ejection port on the LEFT side of the rifle. In reality, except for a few specially made versions, all M4-types eject spent brass through an ejection port on the right. Later in the scene, this shot is repeated, but with the proper orientation.

Continuity mistake: When Pepper is watching the television program about Stark Industries' stock troubles, after Tony's press conference, notice she has a wireless headset in her left ear. When Tony calls her down to the lab, the camera flashes back to Pepper and the ear piece is gone. (00:48:50)
Tony Stark: My old man had a philosophy: Peace means having a bigger stick than the other guy.
Christine Everheart: That's a great line coming from the guy selling the sticks.
Question: How come Tony doesn't die when Pepper hits the button that blows up the roof? He never cleared the roof as intended and it must have been really powerful if it killed Obediah. Tony's chest piece flickers on and off and then the scene fades. They never give an explanation for this.






Answer: Tony, even wearing the Iron Man armour, is light enough that the shockwave of the blast throws him out of the way, so he escapes the majority of the explosion's effects. Stane, in his much heavier suit, isn't so lucky and so gets the full impact, which kills him. The flickering of the chest piece is merely a device to show that Tony is still in one piece, even if injured.
