Continuity mistake: When Dylan is on the boat with Walter and Tressler, there is a bloody cut on his bottom lip, but when he is rescued by the Horsemen minutes later, the bloody cut has suddenly vanished. The cut reappears when Dylan and the Horsemen are talking in the next scene. (01:15:05 - 01:22:15)
Character mistake: At the end of the first movie, when Dylan shows Alma the newspaper article about Lionel Shrike's death, there is an additional article talking about a younger Dylan with the headline "Sad Tale of His Orphaned Son" referring to Dylan, indicating that both of his parents have died. However, in this movie, when Tressler is revealed to be Walter's father, Dylan tells Tressler that Tressler Insurance denied his mother's insurance claim after Lionel Shrike's death. (01:15:50)
Continuity mistake: When Walter finds out about the Horsemen's plan to expose him on New Years Eve, Walter tells a bodyguard to get his father. The bodyguard begins to walk past Walter, but in the next shot, the bodyguard is suddenly at the other end of the room. (01:27:05)

Revealing mistake: When the Horsemen are on the Thames after exposing Walter and Tressler, after Daniel introduces Dylan to the crowd as their leader, there is a shot of Daniel patting Dylan on the back. The shot then cuts to one of the crowds cheering. In this shot, three extras at the front of the crowd can be seen briefly looking at the camera as it passes by. The first is a man in a black coat, red scarf and holding a green glow stick, standing to the right of shot. The second is a woman in glasses standing beside the man. The third is a woman standing to the left of shot wearing a white hat. (01:48:50)

Factual error: When it's 00:00 on January 1st, it's not night in Sydney, it's 11 AM. When they 'reveal' stuff at the end of the movie, and they show that things happen exactly at 00:00 in the night in London, it can't possibly be dark in Sydney, Australia.
Suggested correction: It shows that Sydney is at dusk and is becoming dark, so around 5pm-6pm-ish, not 11am during the day.
Plot hole: Prior to the final show, when the horsemen are performing separately at different locations in London. [Scene X] Jack is busy with his card swap trick. While others are doing their tricks too, [Scene Y] McKinney is believed to be tricked once again by his face sharing brother at another location... Dylan gets a call and then he calls everyone to wrap up and meet somewhere. [Scene Z] Jack also wraps up and leaves the place... OK. Later after the expose in final show McKinney tells the story about how Jack successfully hypnotized his brother [in the Scene Y]. How could Jack be at two different locations at the same time? He was performing somewhere else when he did hypnotism at another location and then wraps up his trick back where he started.
Factual error: The movie shows the FBI operating in London in order to capture the Horsemen. The FBI does not have jurisdiction to operate outside the United States, although they can act with agencies in other countries.
Factual error: When Lula is performing her dove tricks in London she's standing by Cutty Sark, a historical ship museum in Greenwich. Greenwich is south of Thames river. When Walter and his company are showing the positions of the Horsemen on the map of London all of them are shown north of the Thames.
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.
Factual error: After his show Atlas reveals he did his rain trick using rain machines and strobe lights. While this is technically correct it only makes the rain appear to stop, not prevent it from falling. But during his show when the rain is "stopped" we see no splashes on the ground or on people who put down their umbrellas.
