Continuity mistake: Periodically, we see beyond the wall, where it appears to be heavily forested just beyond the wall and a distance beyond. However, once past the wall, the group starts with a cliff down and then it is completely barren, with completely different weather conditions (frequent red rain).
Suggested correction: You're talking about two separate areas. We don't know how far they travelled before coming upon the desolation. The valley was rocky and sparse with trees, but you still see plenty of trees at the edge of the desolation.
Continuity mistake: When Four tells Tris that he found out that he's damaged he is sitting at a table eating. On the table there are two small bowls that look empty throughout the scene, however, when Tris gets up to leave and pulls her hand away from Four's, in the close up shot one bowl is now filled with food, and both bowls are in different positions on the table.
Continuity mistake: Many times in the movie, Romit's hair changes from one shot to another. It goes from very short on the sides to long then back again. (00:59:30 - 01:11:20)
Continuity mistake: When Four is trying to get Tris to return to Chicago with him, when he says "You're coming with me" he has his hand on her neck, but in the next shot when Tris says "I have to go" his hand is on her shoulder.
Continuity mistake: When Four manages to get upstairs, he tries to tell Tris of the bureau's true intentions and that she is being lied to. But she rejects his ideas and joins David in the elevator. You then see Four being escorted away toward the door. But as Tris and David's elevator begins to go up, you see them looking down at Four, who is looking up at them, from the same spot he was in when he was pleading with Tris.
Continuity mistake: When Tris and Four reunite in Erudite a loose strand of hair appears and disappears on Tris' face throughout the scene.
Continuity mistake: When Four uses the wristband to free himself from the cell in Erudite as Tris and Christina engage the guards, as soon as the door opens he drops the wristband. In the next shot when all the guards are down, the wristband has changed positions on the floor.
Suggested correction: It's in the same position, it's just the camera angle has changed. Look at in the first shot you can see 3 windows and the light from those 3 windows, which when the camera moves, we only see light from 2 windows. In the next shot, we only see 1 window and just a little bit of light from the 1 window.
