Continuity: In the opening action sequence, one of the sense-offenders slams wide the front doors of the hideout and begins firing at the police. The camera cuts to the police, who immediately open fire; when we cut back to the sense-offender being riddled by bullets, the hideout doors are securely closed behind him. (Timecode)

Visible crew/equipment: When Preston's apartment is being searched, he walks into his bathroom to find his hidden Prozium capsules. He shuts the door in the camera's face and when you see the interior of the bathroom (with the camera behind Preston) you can very briefly see the cameraman's head. (Timecode)

Continuity: With the dog in the trunk, Christian Bale reaches with his left hand to pet the dog, then cuts to the close-up of his right hand petting the dog, and then cuts back to his left hand doing the petting. (Timecode)

Revealing: When Preston returns to the Nethers he gets out his car and puts the dog down. When he gets back into the car the shot of him getting out is played backwards because the steam/smoke from the engine moves into the car. (Timecode)

Revealing: There is a shot right after the first time the clerics are entering the city from the nethers that you see an APC patrolling the wall road above the entrance. In that shot two shadows are being cast on the road. As the CGI APC passes through them they simply don't cast a shadow on it as they should. (Timecode)

Continuity: The cover of the book Sean Bean is reading reads 'The Poetry of William Butler Yeats'. However, while he's turning over the pages, the poems 'The Detective' and 'The Courage of Shutting-Up' by Sylvia Plath can be seen.

Continuity: When "Father" and Preston are fighting, Preston manages to take the gun away. You can see that both hands are empty, but during the next shot, "Father" still has a gun in his right hand. Then, when they cut to the full shot of father straightening up, his hand is empty again. (Timecode)

Continuity: In the final rampage through the corridor, Preston shoots through the door, killing the guards on his side but also those in the room - we see them falling to one side. But when the corridor guards fall through the doors, in shots from Preston's point of view the guards are visible standing just inside the door before being knocked down.

Continuity: The photo of Cleric Partridge with Mary O'Brien is crumpled and folded when we first see it in the morgue and when Cleric Preston shows it to O'Brien. However, when Preston is sitting at his desk and looking at the photo by himself, closeups of the photo show it as smooth without the signs of wear and tear seen previously. (Timecode)

Plot hole: During the 'Not without incident' scene, Preston has been ambushed. He looks around at all the guards and, in one shot, a guard is standing calmly, with his rifle not pointing at Preston, while everyone else is at DEFCON 5.

Continuity: In the scene where John Preston finds the room with the snow-globe and the record player, he is shown removing and dropping his gloves as he walks the hall touching the wall, prior to discovering the room. As he is shown entering the room, he is also shown removing the gloves that he had just moments ago discarded. (Timecode)

Revealing: When Preston is beating up the soldiers with his studded pistol butts, he smashes the visors off a few of the helmets and you can see the soldiers are wearing protective goggles underneath.

Continuity: The book Sean Bean takes is quite narrow when it's in his pocket, but when we see him reading it later (definitely meant to be the same book), it's about 50% thicker. It was also originally a hardback, but when he's reading it he's bending the cover like a paperback. After he drops it, it becomes a hardback again. Submitted by Jon Sandys

Continuity: In the scene after the destruction of the "TV center", Preston is looking out through a window over the city's explosions taking place. In one shot his right hand is shown holding the red piece of fabric he got from Mary O'Brian. In a scene before that, when he destroyed the "TV center", his right hand was bloody. He could have gone to wash it in between, but that seems unlikely, since his neck wound is still not taken care of. (Timecode)

Continuity: In the scene where Preston is returning to the building to get his Prozium resupplied, the car has on the rims as it drives up to the building. But when he is picked up by his partner and they are driving off, it's quite obvious that the car has on hub-caps instead of the original rims.

Revealing: It's very brief, but during Father and Preston's fight scene, they mirror imaged part of the movie. It's apparent because the sword on the desk has it's handle pointed to the right and you can see the curtain in the background. In every other shot, the handle is facing to left of the room. (Timecode)

Other: Another subtitles related problem. Whenever they show Sean Pertwee delivering a speech the subtitles list Angus Macfayden's character as the one speaking. While this later turns out to be the case I still think they could have done a slightly more discreet job.

Continuity: When you see cleric Preston's wife walking to the incinerator, if you look very closely, you see that they are not the same person, one is a look-alike. [Director Kurt Wimmer reveals the reason for this during one of the commentary tracks (still a mistake, but here's why). The incinerator scene was shot first. When it came to shooting the house arrest scene (which occurs earlier in the film, but was shot later) the actress was nowhere to be found, hence the use of a lookalike.]

Factual error: The real Mona Lisa is much smaller than the 'authenticated' painting shown in the film.

Revealing: At the end when Brandt pulls out the Katana from Father's desk, the close-up shows it's clean and shiny. When he swings it it looks grey and plastic like obviously used for lightness and safety.
