Corrected entry: When Natalie asks Tony for his fingerprint when handing over the company to Pepper, Tony gives his fingerprint while still wearing his boxing glove.
Corrected entry: When Hammer leaves Whiplash to go to the Expo, he leaves him at the Hammer headquarters in NY (Queens, to be exact). The Expo is in California though, and when Scarlet Johansen leaves the Expo, she goes to Hammer to get Whiplash. How can that be when the Expo is in CA and Whiplash is at Hammer in NY?
Corrected entry: After the scene where Tony Stark takes strawberries to Pepper in the office, as he leaves after everyone else he pauses to look at the 'Expo' city model. In the next scene he has the model disassembled and sticking up out of his care as he speeds down the highway. Then in the next scene after he has reassembled the model he blows dust from it. After being driven at high speed, much less all the handling to disassemble and reassemble it, the model should not have any significant dust on it.
Corrected entry: While Tony is being attacked at Monaco he hits Whiplash with the "suitcase" when it is supposed to be in the car with Pepper and Hogan still: they do not toss the case to him until later on in the scene.
Corrected entry: During a scene at the military base a vast selection of military aircraft are shown. One of them is the B2 Stealth bomber. These are ONLY kept at Whiteman Air base in Missouri.
Corrected entry: At the end of the movie, Tony stark sits at a desk with the Initiative preliminary report before him. Before he picks up the report in the foreground for a few moments you can see a news report with an Asian female reporter. However, this report has been looped as you see the same people walk past the reporter twice and her making the same facial expressions.
Corrected entry: When Tony is creating the new element, he deflectes the prismatic accelerator's beam, which pretty much cuts everything it touches before reaching the new triangular core. However, the beam does not cut through the accelerator's own containment glass, and just passes through it. This is seen in the shot where the prism is rotating and the beam is starting to be deflected, as it has its own VFX for the beam diffraction on glass.
Corrected entry: When Pepper and Tony Stark are in the CEO office, just before Tony takes the expo model home, a few things go wrong. Look behind Pepper and see the word Stark, from Stark Industries, appearing and disappearing behind Pepper. Then when Tony Stark opens the door, he looks at the model over his left shoulder. Next shot, he's looking over his right shoulder and is eating a strawberry from the punet he has just thrown in the bin.
Corrected entry: In the scene where Tony is watching his fathers film and reading through his notebook, he picks up a plastic bottle and drinks from it. In the following shot, the bottle has changed to a glass of alcohol.
