Continuity mistake: When Beatrice sees her brother helping the older woman, her brother Caleb asks "Beatrice, do you wanna get the other bags?" Along his shoulder is a visible strap from the bag he is holding. As he starts the line, the bag strap is shown to be vertically down his shoulder, then by the next shot, the bag strap is suddenly positioned slightly to the left. (00:05:30)
Continuity mistake: When Beatrice meets up with her brother Caleb helping out the older lady, Caleb asks Beatrice if she wants to get the other bags. Caleb is first shown to be directly facing Beatrice. Next shot, he's suddenly turned almost 90° to the right with his head now turned in order to face Beatrice. (00:05:30)
Audio problem: As Beatrice and Caleb are walking through the streets, Caleb asks Beatrice "What if she'd been blind or an amputee? Would you have helped her then?" and Beatrice replies "I was thinking about helping her." Neither their lips nor jaws ever move during both these lines. (00:05:35)
Continuity mistake: When Beatrice and Caleb are walking through the streets and Caleb talks to Beatrice about the older woman, Beatrice turns her head to Caleb as she says she was thinking about helping her. In the next shot, she's suddenly looking directly forward. (00:05:35)
Continuity mistake: When Beatrice cuts her hand, one shot shows her making a fist, only half clenched. Next shot, her fist is completely clenched. (00:19:30)
Continuity mistake: When Beatrice and Christina jump from the train to the roof, the overview shot shows Beatrice to be in front of Christina, then the low down angle shows Christina to be in front of Beatrice, then they both land on the roof at the exact same moment. (00:23:30)
Continuity mistake: On the roof, when Eric first introduces himself, the reverse angle shows his hands to be at his side. Then when the camera cuts to being in front of Eric, his hands are now slightly raised, and being held together. (00:23:45)
Continuity mistake: When Tris jumps into the net, in one shot her skirt is down, in the next it is up, showing gray shorts. (00:26:30)
Continuity mistake: As Tris is doing her first fight session, she dodges her opponent's hit and the majority of her hair is shown going over her shoulders. In the next shot, it's now only a few hair strands over her shoulder whilst the rest of her hair is resting along her back. (00:36:00)
Revealing mistake: At the end of the first fighting session, after Tris' opponent has Tris on the ground, Eric gives Tris the signal to get up and the opponent punches her one last time. It is noticeable that the final punch does not hit Tris, but she still reacts anyway. (00:36:15)
Continuity mistake: When Four is throwing the knives at Tris, one of the knifes is thrown right next to Tris' head and her ear is grazed, leaving a cut and some blood around her ear. As soon as all the other initiatives leave the area and Tris goes over to Four, the cut is still there, but the blood has vanished. (00:46:10)
Continuity mistake: When the initiatives are congratulating Tris for standing up to Eric, the opponent she was fighting earlier says "Hey, Tris. That was cool" and Tris replies "Thanks." In the next shot, Tris turns around to Christina and turns even further to the right, but by the next shot she's suddenly back to looking at Christina. (00:47:30)
Continuity mistake: When Jeanine looks at Tris' tattoo, there is hair covering the top of her ear. A few shots later, the hair covering her ear is suddenly behind her ear with only a strand of hair left over it. Then the hair is suddenly back to covering her ear as Jeanine goes to leave. (00:48:50)
Continuity mistake: When Tris wakes up after her fight with Peter, there is a gash shown below her eyebrow and a black eye below one of her eyes. A couple of scenes later, after the war games scene, as they are at the market, the gash below her eyebrow and black eye have vanished. (00:51:25 - 01:04:00)
Continuity mistake: When Jeanine is in Dauntless and congratulates Tris for making the right choice and that she knew her own mind, Tris' hair moves from behind her ear to covering her ear. (00:51:30 - 00:52:00)
Continuity mistake: When the initiatives start playing the war games, Tris and Four take cover behind a shipping container. Four is first shown with his head in front of the container, but by the next shot as he says "Go" to Tris, his head is suddenly behind the container. This has nothing to do with the camera angles. (00:58:00)
Continuity mistake: When Tris is first thrown down the zip line, her hair is behind her head, then when the camera is in front of her, her hair is suddenly over her shoulder, then back to being behind her head. (01:01:05)
Continuity mistake: When Tris is on the zip line, after she does her flying impression and passes by a building, the shot returns a close-up of Tris where there are strands of hair being blown across her face. Next shot, her face is free of any hair strands. (01:01:30)
Continuity mistake: When Tris is nearing the end of the zip line and she notices the other Dauntless initiatives already in the alleyway, there are only a couple of them on the ground from the POV shot of Tris. In a shot of the initiatives telling her to pull the brake, there's suddenly almost a dozen initiatives on the ground. (01:02:00)
Suggested correction: This isn't quite right. From the POV view there are quite a few people at the end of the line. Way more than a couple. Also, from the viewing angle most of them would be stood in front of the black wall (the background to the white cross). Divergents wear black. The background is black. It's at night, which makes things darker. It's at a distance, which makes things harder to see. So maybe it's understandable that from Tris' perspective the view wasn't quite as clear as it was from the ground.
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)
