Continuity mistake: During the last fight with Darkseid, there's changes to what the farm looks like. At one point, instead of the windmill there's a building, which we never saw when Clark drove past the spot. And the overturned truck is missing in a several of scenes even though it should be visible.
Continuity mistake: When Ellie & Fiona are breaking into the garage to steal the gas tanker truck, Fiona's hands are by her side. The camera angle changes, and her right hand is up, holding her rifle strap.
Continuity mistake: Towards the end of the movie, after Boyka gets out of the car with the briefcase, Turbo gets out after him and has a conversation. When Turbo goes back to the car, you see Boyka standing on the side of the road. There is only that one road in all the shots. In the next close up shot of the car door closing, and the car moving, we see the car getting out on to the road from a small by-lane (of sorts)! Where did this road come from? How did the car move places?
Factual error: Major Carlysle's medal ribbons have been sewn on upside down. The Queen's South Africa Medal should be worn first, followed by the King's South Africa Medal, and the KSAM bars should be green-white-orange, not orange-white-green (the QSAM is symmetrical, so looks the same either way up). Sgt Major Saunders, on the other hand, is wearing his medals correctly.
Factual error: After warping back from Iscandar, Kodai looks out of the window. Yuki Mori points him where Earth is. A moment later, he responds to the hailing signal saying that they are now 420,000 kilometres from Earth. Considering that the distance between Earth and the Moon is about 385,000km, Earth is looking unreasonably minuscule from their window. (01:52:50)
Continuity mistake: Jason spits blood onto Joker's chin which changes spot wise and shape wise by the next shot.
Other mistake: Blake jumped through the window, shattering the glass and propelling many fragments through the air and towards/onto Edgar and Zoe, but no-one got cut. (00:34:10)
Continuity mistake: In the beginning, when Billy is talking to the bum (who later turns out to be Tawny), the bum has a glove on his right hand. When he reaches his right hand out to Billy and Billy gives him a subway token, there is no glove. It's back in the next shot.
Continuity mistake: When one of the robbers is walking away with 4 bags stuffed with money, you can see a large stack of money bills sticking out of the bag. In the next shot the bills are gone. (01:04:40)
Continuity mistake: After RVD is shot by the lone motorcyclist he goes home to take care of his wound. You can see that he was shot in his LEFT shoulder. When he goes to the bathroom and takes off his shirt, the wound is on his RIGHT shoulder. After bandaging up his wound, he finds his wife bound and gagged and his daughter has been taken. He goes out to the garage and you can see his LEFT shoulder is now bandaged. (00:58:50 - 01:01:55)
Continuity mistake: Throughout the motorcycle/police car chase they used two different motorcycles made 50+ years apart and just painted them both black. One is a 1940s Harley Davidson with a springer front end and the very recognizable horn below the headlight, and the other is a late 1990s (at the oldest) cruiser with a front end that's completely different in every way.
