Continuity mistake: When Alma realises there is a separate newspaper inside the newspaper she is reading, there is a shot focusing on the newspaper that shows an article focusing on the death of Lionel Shrike. In the next shot, when Dylan reveals himself on the bench, the top left corner of the newspaper is suddenly folded over, presumably being blown by the wind. (01:51:40)
Continuity mistake: When the Horsemen are greeting the crowd at the 5 Pointz show, in a shot from behind the three while they are waving, Merritt is waving with his right hand before lowering it. When the shot cuts to an angle in front of them, he is shown lowering his left hand. (01:38:15)
Continuity mistake: When Cowan picks up the dummy after realising it isn't actually the Horsemen, he grabs ahold of the dummy by grabbing the right arm with both hands. Then it cuts to a closer shot of the dummy where his right hand is holding onto the dummy's abdomen. (01:37:50)
Continuity mistake: When the agents tackle the Horsemen dummies, Cowan jumps onto the platform after the agents fall to the ground. At this moment, he is facing them directly forwards. When the shot cuts, his body is at a rotated angle, facing away from the agents. (01:37:47)
Continuity mistake: When the agents are trying to open the Elkhorn safe, an agent places a device next to the dial before pulling the dial out. The device that the agent is holding is positioned next to the dial, but when the shot cuts, it is pushed against the safe. (01:33:15)
Continuity mistake: When Thaddeus asks Dylan if he wouldn't mind reenacting his look of absolute befuddlement, there is a shot of Dylan being filmed by the camera crew shown from the POV of the camera. In the background, Cowan and Thaddeus's assistant Hermia can be seen standing next to each other. But in the next shot, when Dylan says "Open the safe," Cowan and Hermia are further apart. (01:33:08)
Continuity mistake: Dylan receives a cut on his cheek and neck during his fight with Jack. While speaking with Alma shortly before going to the Elkhorn building, the cuts appear to be faded. But in the following scene, after they have discovered the Elkhorn safe has been removed from the building, the cuts are bloodier. (01:27:45 - 01:29:37)
Continuity mistake: When the FBI agents start running after realising the Elkhorn safe is missing, Evans can be seen positioned close to the other agents and is aligned with two armed men. In the next shot, he is running further ahead than the other agents by at least a metre. (01:29:20)
Continuity mistake: When Cowan is telling Dylan about the Elkhorn safe, whilst he is saying "The money's in a vault inside a warehouse in Queens," he is looking at Dylan. But in the next shot, Cowan is looking at the laptop. (01:27:01)
Continuity mistake: When Cowan is showing Alma the video of the Elkhorn safe on the laptop, he says, "Here's the safe," and begins moving his hand over to the other laptop. In the next shot, his hand is suddenly back over the laptop that had the Elkhorn safe video on it. (01:26:44)
Continuity mistake: When Jack is about to flee in the FBI car, Dylan runs up to the car and places both of his hands on the front passenger-side window. When the shot cuts, his left hand is placed on top of the car. (01:20:51)
Continuity mistake: When Dylan and Jack land on the mattress at the bottom of the garbage chute, Jack picks up some papers and leaps over Dylan. When this happens, they are surrounded by garbage bags, but there are no bags on the mattress. A few seconds later, after Jack runs away, a garbage bag has suddenly appeared on the mattress in front of Dylan. (01:19:39)
Continuity mistake: When Jack jumps into the garbage chute, Dylan places his left hand on the wall above the chute when he reaches the bottom of the staircase. When the shot cuts, his left hand is placed on the pipe above the garbage chute. (01:19:12)
Continuity mistake: After Dylan and Jack have ran out of the apartment, Fuller tries to free himself from the jacket stuffed down the garbage disposal. While doing this, he is inside the sink, then leaps out onto the floor. He is standing upright when he leaps out of the sink, but when the shot cuts, he is leaning forwards. (01:19:06)
Continuity mistake: While searching the apartment, Fuller finds a Lego building on top of some red velvet cloth placed on a table. There is one corner of the table that doesn't appear to be covered by the cloth. But in the next shot, the corner is suddenly covered by the velvet cloth. (01:16:55)
Continuity mistake: When Alma chuckles at Dylan after he removes the teleportation helmet, Dylan can be seen on the right-hand side of the shot. When the shot cuts, he is shown brushing his hair with his left hand, which should have been visible in the previous shot of Alma chuckling. (00:36:21)
Continuity mistake: After Thaddeus has walked into the fake vault, Dylan asks what was with the helmet. At this moment, Dylan starts to remove the helmet with both hands. Thaddeus then replies, "My fun," and Dylan can be seen in the background removing the helmet with one hand. Then, when the shot cuts to focus on Alma, he is removing it with both hands. (00:36:18)
Continuity mistake: Just after Dylan has landed in the fake vault, he is standing while the door starts to open. At this moment, his left foot is pointed straight forwards and his right foot is rotated a few inches to the right. When the shot cuts to show Thaddeus walking up to the vault, both of his feet are rotated further to the right. (00:36:09)
Continuity mistake: When Thaddeus is showing Dylan how the Horsemen performed their trick, he and his assistant start lowering the sheet around the teleportation device. Once he finishes lowering the sheet, there is a cut and suddenly he is standing several feet away from the device. (00:35:50)
Continuity mistake: When Dylan and Evans are walking through the FBI office, just as Dylan says "Get Turkelson" and Evans replies "He's in Atlantic City," Dylan has his right arm lowered. In the next shot, his right forearm is raised so that he can point to Cowan. (00:24:30)
Answer: The mirror was inserted at an angle, so that the reflection was the ceiling and not what was in front of them. It's the same principle for how periscopes work.
