Revealing mistake: John Kramer's chain first goes on the side of his stomach, and then it's on his backside... impossible, otherwise the chain would split him. (01:35:47)
Revealing mistake: Just as the first credits roll, when the cheerleaders dance, check the African American, Caucasian, and most noticeably, the Asian American people behind the team. They are blatant, creepy-looking, unrealistic CGI characters. (00:01:18)
Revealing mistake: Throughout the dive boat interior scene - after they dive on the wreck - various hanging items are swinging around randomly to give the impression the boat is rocking on the water. However, none of the key light shadows - from the exterior sunlight - move at all, indicating the boat is entirely static in a studio.
Revealing mistake: When the oil starts gushing, one can see a rectangle on the ground with different coloured grass, where the pumping mechanism to achieve the effect was buried.
Revealing mistake: Ian stands on the rooftop, with an elevated highway to the right of the screen, some distance from the building. The right-side rear view of Ian reveals the elevated highway much closer, practically against the side of the building. The CGI elevated highway's height compared to the rooftop also varies, being lower when Ian sits, and the support posts are not even flat against the underside of the elevated highway. (00:41:54 - 00:42:20)
Revealing mistake: Alberto forces minor Alan to smoke a cigarette. Alan appears to be puffing on the cigarette, but no smoke comes out of his mouth when he "exhales". At one point, Alan is inhaling and the red tip of the cigarette (prop) blows outward. (00:36:45)
Revealing mistake: When Miller is stopped by police and looks into his side mirror, it looks like the police officer is coming out of the passenger side of his car. The front view shows the officer emerging from the driver's side, like he should be. (00:22:00)
Revealing mistake: The airplane windows on both sides of the aisle are solid white ovals, with no variations to indicate the airplane is moving in the sky. (00:40:30)
Revealing mistake: The position of the lamp (upright or tilted) to the left of the screen varies, and the way the light is cast on the wall above and below the lampshade is not realistic. For example, when the upper part of the lampshade is angled away from the headboard, the light projects below the lampshade shorter toward the left of the screen, not elongated. (00:01:00 - 00:03:00)
Revealing mistake: There is a glimpse of a bench on the porch landing, roughly parallel to the steps where Jake is sitting with his back at about a 45° angle to the railing. Front views of Jake show the bench oddly angled upward as though it ascends like the steps. (00:38:10 - 00:39:12)
Revealing mistake: More than once, when speaking to their robot doubles, it's obvious that both Charles and Elaine are actually just talking to nobody, given their mannerisms.
Revealing mistake: While inside the tunnel in Rome, before the yellow Fiat makes a U-turn multiple skid marks from previous takes are visible. Though one might pressume that the marks were already there, they are at the same spot and have the same pattern as the skid marks that the cars make seconds later.
Revealing mistake: After Kristin tramples on the muffin, it should crumble/flatten, but it starts to inflate back into shape. (01:17:45)
Revealing mistake: Vivian talks on the phone as she walks towards the camera. A couple walks behind her in the opposite direction. A bicyclist emerges from the left-center side of the screen and heads straight across the path, perpendicularly towards the couple. The bicyclist "disappears" behind Vivian, just before he reaches (crashes into) the couple, and the camera cuts to Carol. Seconds later, Vivian still walks towards the screen, and a different person walks where the couple was. (00:14:38)
Revealing mistake: When the Minotaur is born, he doesn't cast a reflection on the building right next to him.
Revealing mistake: Neither driver, Justine, nor passenger, Billy, were visible in the car when it got spun around by the Jeep. Even if both got bent over from the impact, the upper parts of their bodies should have been visible as they were both erect in their seats when the man opened the door to check on them. Also, the car doors were so smashed in that the man should not have been able to open the driver's door (at least not without some force or "Jaws of Life"). (00:19:25 - 00:19:57)
Revealing mistake: The dog may be trained to go down the hallway, looking for a treat, but not to encounter Henry and "act" like he is happy to see a family member who just returned from vacation. Instead of being excited to see Henry, the dog's body language is indicative of stress or discomfort - tail pointed down with no wagging, slight cowering posture, weight shifted backward, and he even starts to back away from Henry. When lying next to Henry, the dog tries to crawl over the side of the bed. (01:17:45 - 01:31:00)
Revealing mistake: The ship is being attacked by a megalodon. The USS King is supposed to be in open ocean. When three sailors run to the left, we can see the ship is next to a dock. (01:01:35)
Revealing mistake: When the Barrys cross through the glass door, for a couple of shots, Young Barry's face is replaced with a non-realistic CGI face with features that don't match the face contour at all.
Revealing mistake: During the negotiation for the second murder, Happy Anderson writes a "You HOPE she suffered" note, but shreds what looks like a "You HOPED she suffered" note - they are two different handwritten notes. (00:35:00)
