Continuity mistake: A few minutes after Lee puts a bandage on Hugh's forehead, it disappears completely in one shot (as does the cut it was covering), before reappearing a moment later, but in a different position.
Continuity mistake: Joe is looking through his yearbook while Marie chats with the old headmistress. He finds the page with Adrian's photo. At first, the name under the photo is Adrian Pryce. In the closeup shot, it now reads Adrian Doyle Pryce. (01:12:20)
Continuity mistake: When looking at the dog from the bedroom window, there are 2 windows in the room facing the dog. When we see the window from outside only 1 window is lit up, despite both being in the same room. (00:11:30)
Plot hole: Even if someone would make all nuclear powers launch their nuclear missiles and then destroy them you still wouldn't have a nuclear weapons free world as most of those nations have plenty of nuclear weapons in reserve. A lot would be even be armed and ready to go for a possible second strike. (01:24:10)
Other mistake: When the driver of the ZR1 corvette changes gears the emergency brake lever is visibly up. (00:53:00 - 00:53:55)
Continuity mistake: In the scene where Heather runs through the fairground she grabs onto the back of the Ferris wheel seat and is taken up in the air. Leatherface throws the chainsaw at the cop and the next shot shows Heather coming back down the other side of the Ferris wheel. But she should be on the inside of the carriages as it just spins round on an axis. These kinds of wheels don't "twist" at the top otherwise the rider would just be staring at the inside of the wheel the whole time.
Continuity mistake: In the scene when Papi is in the back of the white Fodge driven by Stig, the Ford Bronco driven by Bobby crashes into Stig's white Dodge twice - both headlights are smashed out. Once the Bronco goes into the ditch and comes back out, the passenger side headlight isn't broken.
Visible crew/equipment: After the jewelry heist, outside in the backyard when Ross looks for Parker, the camera crew is visible through the window, about three or four shadows appearing on the window reflection. (01:42:35)
Revealing mistake: At the end of the film when John Moon is digging a shallow grave for the dead girl (who has been dead for days, and spent additional days in a freezer also). You can see the dead girl breathing by the way her arm is moving on her chest. (01:46:00 - 01:47:00)
Continuity mistake: We discover that because time is non-linear in the Further, it was Josh's spirit who was the one knocking on the door in the original film. However, the knocks we see Josh make in this film don't quite match up with the original film. In this film, he knocks many times frantically, whereas in the first film, we only hear a few faint knocks in rounds of three. (The film tries to mask this by inter-cutting footage from the first film to illustrate the point, but it still doesn't quite match up).
Factual error: Halcombe takes a left turn to park in the parking lot of the Army/Navy Surplus store on 4th Avenue. This means he was approaching from C Street, which is a one way street in the opposite direction between 4th and 5th Avenue. (00:15:00)
Plot hole: According to the flight recording, Odyssey was on an uncontrolled pull towards the Tet as Jack says, "We're not getting away from this thing." So even if Jack jettisoned the sleep module where Julia was in, the module should not be able to get away as the whole ship is being pulled towards the Tet.
Suggested correction: It can be assumed that the jettisoned module has enough "jettison power" to force it away from the command pod. And in turn that force would move the pod further towards the Tet. It's reasonable to assume the Tet couldn't pull the module that was moving away, under dramatic force, and to which it didn't have line of sight (which was blocked by the pod).
Continuity mistake: When Dave is shot by Mindy while training, there are two bullet holes in his jacket when he has only been shot once at that point.
Character mistake: In the scene where Billy is called to the crime scene of Andrews' murder, Andrews' body is shown with a wound on his chest. Later in the movie though, Billy is questioning Todd Lancaster. Todd Lancaster says that he saw Andrews get shot in the head. (00:52:00 - 01:25:00)
Character mistake: In Pitch Black they established the system they crashed in (M-344/G) had 3 stars. Jack stated it when the 2nd sunrise started, and the solar system model also had 3 stars. In this film when Boss Johns starts asking about M-344/G he says it is "a backwater system with 2 suns and 1 habitable planet."
Factual error: They inject the infected Brunel with antibiotics to fight the bacteria, however there is no pulse and that means the antibiotic can never spread through the body, as there is no blood circulation.
Visible crew/equipment: In the opening close up shot of the eye, you can see a reflector screen reflected in it. (00:04:10)
Continuity mistake: The Counselor's watchband during the long phone call about choices, fate, and grief with Jefe changes the direction in which it is latched several times throughout the scene. It is quite prominent because it is on the arm he is using to hold the phone. (01:35:00 - 01:40:00)
Continuity mistake: At the beginning, as Raimund is crossing the bridge in the rain, his umbrella turns inside out, but as it flies away to the river, it is not turned.
Continuity mistake: When Wanderer and Melanie first start to work together to escape, she walks out onto the balcony above a pool and places her hands on the railing, very close to one of the vertical dividers of the railing. The camera pans down to the pool then cuts back up to her. Suddenly, she is equal distance from the vertical dividers on her left and right, and the doors and windows she just walked through have disappeared behind her. (00:22:50)
