Revealing mistake: When Viggo pushes the car off the edge and it hits the ground, as it rolls you can see that the engine/transmission, drive shift and tank have been removed. (01:26:00)
Revealing mistake: When Lucy is chained and locked up in the room by the Korean drug cartel, she is hit in the stomach by the Korean guy. Drugs start leaking into her stomach and her body, and she starts shaking and going up the wall and ceiling. When she is leaning against the wall and crawling up it, the way the gravity affects the chains and her hair shows that she is actually lying on the floor. (00:25:20)hamzehlou
Revealing mistake: When they leave the caravan park, look at the wheels of the caravan they are set up to rear steer like a truck trailer, rather than a normal caravan. When they exit the park the caravan tilts, giving a good view of the set up underneath.
Revealing mistake: When Four injects Tris with the serum before taking the test for the first time, it is very apparent the syringe is not injected into Tris' neck. The tip of the syringe is merely just touching the skin of Tris' neck and the syringe is shown moving around her neck. (01:07:30)Casual Person
Revealing mistake: In the Kentucky church-massacre scene, Harry briefly scuffles with a man in a light blue sweater. Harry elbows him in the ribs, sticks a grenade in the man's pocket, spins him around and delivers a crushing blow to his neck, then hurls him head-first into a wall. Throughout this sequence, the man is obviously a live human being. However, a fraction of a second before he impacts the wall, he transforms into a life-size rubber dummy before our eyes, in mid-frame, without any obvious camera cut. This demonstrates the complexity of the scene - it is a digitally-edited collage of action sequences almost seamlessly strung together into what appears to be one long traveling shot.Charles Austin Miller
Revealing mistake: As Glenn, Blake and Monica are being surrounded by zombies, as Monica asks "Fucking hell, how many more of these are there?", in the background you can see a zombie sitting astride his victim, flailing away with a hammer or hatchet. It is obvious that he is just swinging his arm back and forth, without connecting with anything. It looks as if he is dusting, not slaying someone. (01:23:50)Twotall
