Quantom X

Continuity mistake: Before the Jackal attempts to assassinate the First Lady, the Chairperson calls the Surgeon General to the podium. In the shot from behind as he shakes her hand then walks up, you can see to the right there is the shadow of him and the podium, with no other shadows visible around him or near him. But then it cuts to a wide angle from in front in the crowd and the shadows are all different, with some even now behind him from the building. (01:36:25)

Revealing mistake: When the Jackal shoots Douglas, you can briefly see the outline of one of the blood packs under his white shirt. (01:32:50)

Continuity mistake: After The Jackal shoots Koslova, he places a pillow under her head to prop it up. Once at rest, her face is clear of any hair. It then cuts to the Jackal as he tells her about her blood being black and she has 20 minutes to live, then back to her. And now she has some strands of hair down over her left eye. (01:25:40)

Revealing mistake: When The Jackal shoots Koslova through the couch, you can see a small hole in the fabric of the couch already there, before it's made larger by the special effects team's work. (01:25:05)

Continuity mistake: As the helicopter is coming down for Declan and Preston, in the wide shot Declan is standing outside the car leaning against the door facing forward. But as the chopper draws near, he turns his body around and looks at it. It then cuts to a close up of him and suddenly he's facing forward again. (01:20:30)

Character mistake: At the docks, The Jackal draws his pistol on Declan to kill him, but Koslova returns fire to save Declan. The Jackal's pistol is silenced, however Koslova's is not. And they engage in a fire fight and foot chase on a dock crowded with people. Koslova appears to be using a Beretta 9mm pistol, which is loud in it's own right. Yet as they exchange shots, not a single civilian near by reacts to the fire fight or panics whatsoever. She even runs past a few and pushing them out of the way waving her gun around, and they merely treat it like an annoyance. There was plenty of people around to hear the loud gunshots of Koslova's pistol and could see the Jackal firing with his as well. (01:12:20)

Continuity mistake: As Declan is holding Koslova as she dies, her hand is on the side of his face. As she takes her last breath, you see her index and middle finger next to his ear, while her ring finger and pinkie are bent in and touching his neck. It then cuts to a shot of Declan's face as he reacts to her death, and suddenly her hand is flat on his cheek with all fingers on it, just before it drops as the life leaves her. (01:28:10)

Continuity mistake: When Witherspoon is shot in the head by The Jackal, we see a large blood splat hit the wall behind him. But later as Declan is running through the house while the FBI and paramedics are there, he runs past this same spot and now the blood splat is much closer to the corner of the wall. (01:24:30 - 01:27:00)

Continuity mistake: The Jackal kills Witherspoon, who stumbles back against the stairwell wall and is in a sitting position. He's seen behind Koslova as she's kneeling behind the couch trying to shoot the Jackal back. Witherspoon's body is then shown again after the Jackal shoots Koslova and is approaching her as she tries to crawl away. Witherspoon's body changes positions in several ways. Most notably, his head is now sitting more straight up and closer to the doorknob. His legs are bent up more with his feet now almost touching the table leg. And also the rug he is on is bunched up more, having only 1 large bump before, but now having two. (01:24:50 - 01:25:20)

Continuity mistake: Once the Jackal sets off the music at Isabella's house, making Koslova rush outside, the other FBI agent upstairs starts running down them when the Jackal shoots him though the stairs, leaving many bullet holes. As he falls down the stairs though, they seem clean and unscathed. A few shots later as the Jackal is coming out from under the stairs, you can now see there is damage to them. Most notably the large chunk of splintered wood on the 5th step up that appears. (01:22:45)

Deliberate mistake: Declan and Preston are hanging out at an airfield in a blue car when they realise one of the numbers in the notebook they have is an FBI access code that The Jackal now has. In establishing shot of this scene you see the blue car sitting more towards the left with Declan on the hood. Then when Preston calls in this finding and they get a helicopter to come pick them up, in the shot with the chopper coming the car is now suddenly much further to the right. It seems they had to move it during filming to allow a place for the chopper to land. (01:19:05 - 01:20:30)

Continuity mistake: At Isabella's house, Koslova is walking with her into the kitchen as the FBI is placing her in protection. As they are walking, Koslova has nothing in her mouth and as the camera pans around, she starts to lift her right arm up to her face with her cigarette in her right hand. The camera cuts to a frontal view of her, and suddenly she has a cigarette in her mouth and is now taking it out with her left hand. (01:18:45)

Quantom X ★

Continuity mistake: After the mole in the FBI room is discovered and escorted out, Preston shuts the door and steps back into the room. In this shot you see two of the FBI sitting on a couch next to the door. The one on the left has his left arm relaxed beside him and the one on the right is looking straight forward. It then cuts to a close up of them before the guy on the left speaks, and now his arm is ridged with his fist balled on the couch, and the guy on the right is now suddenly looking to the right. (01:17:10)

Character mistake: In the Chicago-Mackinac race, the Jackal is trying to blend in with the other boats. But he has an American flag visible on his boat. When in the race, the boats only use fleet pennants. Other flags indicate "Not in the race." So the coast guard that waved at the Jackal would have realised this. (01:07:40)

Trivia: Gerard Butler and his crew are loosely based on former ATF agent, Jay Dobyns, who consulted on the film. Dobyns is best known for his undercover work and his willingness to infiltrate crime organizations, much like Gerard Butler. Dobyns makes a cameo in the film at the bar Donnie works at in LA, closing his tab at the bar.

Trivia: The $100 bill in the closing credits has the serial number DOT00002018. Which stands for Den of Thieves 2018, the year it was released. (02:24:00)

Character mistake: When Big Nick and his team are first discussing the theft of the armored truck early in the film, Nick is eating and turns to one of his partners and asks for him to give him the "Pepto", or pepto bismol. You can see in this shot the bottle of pepto bismol is already sitting on the desk next to the guy, but then the guy opens the drawer and mimes the movements acting like he's pulling it out and setting the bottle on the desk. (00:23:25)

Trivia: The black body armor that Gerard Butler wears in this movie actually has a patch on it next to the word Sheriff that says "fuck you". (02:13:45)

Visible crew/equipment: As the crew is leaving the salvage yard where the garbage trunk went, they are in a black SUV. In the shot of them leaving there is a close up of the corner of the bumper, and in it you can see the film crew and director's chair reflected in the bumper. And as they are pulling away it appears the film crew is also reflected in the tail gate of the SUV. (02:00:25)

Quantom X ★

Continuity mistake: When Big Nick kidnaps Donnie and they are questioning him at the motel, he sits in a chair and Big Nick walks past him setting a bottle of whiskey on the table next to Donnie. It's visible there most of the time, but after Big Nick slaps Donnie and says don't be a smart ass, in the next shot from behind the bottle disappears. (00:29:45)
