Factual error: New Asgard is in Tonsberg, Norway, but was filmed in Scotland. The truck Hulk and Rocket use to get there has a UK licence plate (SW61 5PN), whereas Norwegian plates use two letters followed by 4 or 5 numbers. Plus the pizza boxes in Thor's house have a phone number in UK format (01632 960776) not Norwegian. In fact, the 01632 area code is specifically designated for fictional use in the UK. Norwegian telephone numbers use fewer digits. (00:48:50)
Factual error: Shazam catches the bus with his hands, but it lands on his hands and face by the windshield. This puts the entire weight of the bus being supported by just the front windshield held by Shazam's hands, plus the momentum of it falling from the bridge hitting him. No way the glass could support all that and not break. Especially since it already cracked from just a guy falling on it.
Factual error: When we see Elton John's father Stanley in RAF uniform at the beginning of the film he is wearing other ranks' uniform. Stanley was commissioned in 1944, three years before Elton was born, and served as a commissioned officer until his retirement as a squadron leader in 1963. He should be wearing officer's uniform.
Factual error: Speed radar guns work by measuring the speed of an object that is either approaching or moving away from it. So when it shows Sonic running across, the beam giving the measurement wouldn't work, and he would have barely even registered on the device. (00:04:44)
Factual error: The USA map is inaccurate for the year it is set in. It shows all states but in 1886, many of the northwest states (e.g. Montana, Idaho, the Dakotas) weren't states until 1889+.
Factual error: Parker is looking for the phone her mom hid. She is moving a box of cereals. The cereal ingredient label has a few joke entries you may Miss at first (goat hair, bitter almond paste, false eyelashes), but the nutrition facts tab is also incoherent in a way too subtle to be a deliberate joke; sub-categories of each macronutrients exceed the total. For instance, it has 5 g of Fat in total, but 25 g of Cholesterol and 56 g of Saturated fat (at most it could be mg). (01:00:25)
Factual error: A piece of ship that size crash landing into a planet and not being destroyed would be an extinction level event. The asteroid that supposedly killed the dinosaurs was a lot smaller.
Factual error: In the antique shop, Woody is at a point where he's at the center of a tug-o-war between two sides, with the "bad toys" pulling on his draw string for his voice box. The voice box can still be heard spouting its lines, despite the fact that the tension on the string is never released allowing it to draw the string back in, which is what makes the sound. It can't make it's sounds with the string continually out in the pulled position.
Factual error: The silhouette elephant weather-vane is incorrectly made and would never point into the wind because the elephants are too far forward.
Factual error: Bobby's shotgun hit blasts a hole through the head of the first zombie entering the store, but the zombie directly behind it, as well as the barricade, are unscathed. The shells can hardly penetrate this much, wide and clean through the head and then disappear with no trace. (01:35:05)
