Continuity mistake: In Monaco, Stark smashes his head against a green car. When he falls on the ground there's a red sign with the numbers 885 on it. In further shots the sign has disappeared.
Continuity mistake: During lunch with Ivan, the way Hammer's napkin is tied around his neck and laid on his shirt keeps changing between shots, despite Hammer not touching it.
Continuity mistake: When Stark and Rhodey break through the roof of the house the hanging debris from the hole above keeps changing depending on the angle focusing, with hanging parts that appear or disappear randomly.
Continuity mistake: The scene in the Monaco lounge when Tony Stark and Justin Hammer are sitting down at a table with Christine Everhart to give an interview, Hammer sets his drink on the table while he's standing but then the shot immediately cuts to him sitting down with the drink still in his hand.
Continuity mistake: When Hammer takes the parrot away from Ivan, the Russian's black jacket keeps swapping from opened to closed between angles.
Continuity mistake: At the Stark Expo in the beginning, when Tony Stark talks about "kicking back", as he says "on my best day" his hands are by his sides, then we cut to a different angle and his hands are instantly behind his back.
Continuity mistake: In the beginning when Tony's press conference is on TV in Anton Vanko's home, the dialogue exchange between Tony and Christine Everheart has more talking than that same scene in "Iron Man" at the end. In "2", Christine mentions that Tony hates body guards in the exchange, but, this is never said in the first "Iron Man".
Continuity mistake: When Ivan crashes Stark's car during the race there is a close-up of Tony's face showing a red scrape on the cornea of his eye. When he puts the suit on there's another close-up of his face inside the armor and both eyes are completely undamaged.
Continuity mistake: Before Hammer starts eating dessert (and thus much before the "moving spoon and cherry" continuity mistakes), there's a back angle where he dips his spoon into the dessert and starts eating. The angle cuts to a front view with the spoon laying spotless on the saucer, and Hammer saying "I'll start with dessert", and then repeating the whole previous scene as if it were the first time.
Continuity mistake: At the beginning of the film Tony Stark is at the Expo wearing a tuxedo with a white shirt under it. When he leaves the stage and checks his blood toxicity it changes to a black shirt.
Continuity mistake: Ivan doesn't have a toothpick in his mouth when he was handcuffed, his head covered with a hood, and put in a van. As soon as the hood is taken off and he walks towards Hammer, one suddenly appears in his mouth after an angle change.
Continuity mistake: During the questioning by the Senator the jars on the congressmen's table disappear in the angle from behind, only to reappear in the front ones.
Continuity mistake: During the Monaco part of the film,when Hammer and Christine Everhart are talking at the table and the camera is angled towards her,Christine is holding her phone in her right hand and her recording device in her left. When the camera changes angle to face Hammer and Christine stands up to leave,the phone and recorder change hands.
Continuity mistake: When Hammer breaks Ivan out of prison and they have dinner together in the aircraft hanger after, the butler fills up Ivan's glass with red wine but in the next shot both glasses (wine and water glass) are full and he has a bottle of vodka even though we don't see the butler give him the vodka or fill the water glass.
Factual error: In the hidden scene the car stops and you get a flash of the front of the car the New Mexico license plate is in focus (to show were they are). However in New Mexico they only issue you one plate to be used at the rear of the car.
Other mistake: Justin Hammer picks up the M134 like it's a feather. In reality, it's a hundred pound gun, even a big bloke would have to work hard to pick something like that up.
Continuity mistake: Near the end of the Whiplash-Iron Man racetrack fight scene in Monaco, Whiplash has Iron Man hooked with his right hand whip and Iron Man is down on one knee. The shot switches to focus on Whiplash's face and it appears as though his left hand is forward and hooked to Iron Man. This can also be seen in the 'suitcase suit' clip.
Continuity mistake: Throughout the entire film, the black and white shapes in the hair of Ivan's beard are different in almost every single scene he's in.
Factual error: As the credits roll, the songs are featured. The song 'Highway To Hell' by AC/DC is printed as Written by Angus Young, Malcolm Young, and Brian Johnson. It was not actually co-written by Brian Johnson as he was not yet the lead singer of the band. It was actually written by Angus Young, Malcolm Young, and Bon Scott, nee Ronald Belfort 'Bon' Scott, who was the lead singer then until his death in 1980, after which, Brian Johnson was then hired as the new lead singer.
Continuity mistake: During the first fight between Tony and Ivan he's got his right hand's whip wrapped around him then camera cuts to Ivan and it's suddenly his left hand's whip.
Answer: He wanted to do something nice for her, but since he is a pretty self-absorbed, shallow multi-billionaire, he forgot about her allergy. He remembered that there was SOMETHING about her and strawberries, but misremembered and thought it meant she really liked them. He makes a simple human mistake, not out of meanness or spite, but because he honestly does not remember.
