Continuity mistake: When Agent Cowan is asking the FBI director what happened, she says that they are gone and tells the man beside to come with her. She and the man then start walking, with the FBI director walking a couple of feet ahead of the man. In the next shot, the man is still behind her, but suddenly slightly closer. (01:53:50)
Continuity mistake: At the Royal Greenwich Observatory, when Dylan picks up the picture of his father and Thaddeus, he grabs the picture holding the bottom of the left hand side, but in the next shot, he is suddenly holding the picture much further up along the side. (01:55:25)
Continuity mistake: When Dylan enters Thaddeus' prison cell and begins looking around, there is a clock on the wall showing 7:52. As Thaddeus walks into the cell seconds later, the time on the clock is suddenly 7:55.
Continuity mistake: When Dylan is leaving the prison with Thaddeus, it is night time. But later on in the movie, when the FBI director and Agent Cowan are watching the CCTV footage of Dylan and Thaddeus leaving the prison, the time on the CCTV shows them leaving the prison at 14:10, the middle of the day.
Continuity mistake: In the first Now You See Me, Dylan said before his father got into the safe that was dropped into the river he gave Dylan his watch to hold so he could count the seconds until he escaped, but in Now You See Me 2 there's a flashback that showed what happened before his father got into the safe and he does not give him his watch. Instead it shows Dylan and his father both with a watch and synchronizing them together.
Continuity mistake: When Walter Mabry is explaining how the Horsemen ended up in Macau he walks over to sit on the couch to show the slideshow of the plane trip. As he walks over, Atlas is not on the same couch as the other Horsemen, but when Walter goes to sit down he squeezes between all of the Horsemen with Atlas now on the end of the same couch as everyone else.
Continuity mistake: At the launch party, Dylan is holding a playing card with 'The Fool' written on it. Dylan turns the card around whilst holding the card on the right hand side. From a different shot, he is holding the left hand side.
Continuity mistake: Jack is shown wearing a security guard uniform throughout the entire infiltration of the launch party. When the party has been intercepted and Jack is exposed to everyone, he is still shown wearing the security guard uniform, but when the Horsemen are on the roof minutes later, Jack is suddenly back to wearing his leather jacket and T-shirt. Even if this is needed for the story and some time had passed between scenes for him to change, Jack was being chased by the FBI and was in a hurry to escape the building, so he would not have had anytime to change back, nor would he have risked wasting any time changing his clothes anyway.
Continuity mistake: When Daniel is performing in London, there is a wide angle shown in the scene, with Daniel under blue lighting. In all other shots in the scene, he is under white stage light.
