Continuity mistake: Ellis leaves in in his dad's Jeep (model year 2005-2007) and in the very next scene he is driving a newer model.
Continuity mistake: There are missing boys in the movie. At the end of The Maze Runner, there are 8 boys that get out of the maze besides Teresa. At the beginning of Scorch Trials, only 7 get in the compound. When Thomas shows the stolen card to the others, there are 6 of them and they all escape with Teresa and Aris. When they get out the mall and enter the city, there are 5 of them besides Aris and Teresa. The last boy (called 'Jack' by cast and crew) dies in a deleted scene, the other two boys simply vanish without a trace or explanation.
Continuity mistake: After Rey touches Luke's lightsaber she begins to have the vision, and when she falls to the floor the blaster is missing from the back of her belt, but after she "sees" Luke and R2 and then stands up the blaster is back again, tucked into her belt (even though Rey's having her vision of things all around her, she herself is not a vision).
Continuity mistake: Whenever young Riley is pulling the wagon around the house, Fear stops her at a white cord in an outlet. In the next shot, it is a black cord.
Continuity mistake: In the scene near the end of the movie where the kidnapped father overpowers one of the bad guys and grabs his gun, he shoots out the front tire of the truck and he and Justin go running away. In the very next scene, Tyler and his buddy jump in the truck to chase the father and son and the tire on the truck is miraculously fixed and inflated.
Continuity mistake: Sue's hairstyle, as well as the texture and length of her hair, and the color, changes from scene to scene, and even at times from shot to shot. This was due to movie re-shoots.
