Revealing mistake: When the bartender recognizes Harold and calls the cartel leader, his phone screen stays on instead of turning black and shows that he's still on the lock screen displaying the time, not actually calling anybody. (00:49:30)
Revealing mistake: After Mel is killed, Scott drives away in a truck that they were just hiding behind during the shoot out. But there is not a single bullet hole or sign of damage to the truck.
Revealing mistake: Annie hears the sound of scribbling in the distance and follows the sound into Charlie's room. When she enters at 1:26:13, you see Charlie's doodle book on the bed being written in and the pages flipping on their own. If you look to the left of the bed, there are a few visible wires running from the book towards the wall to turn the pages. In the photos, they can be seen towards the bottom of the nightstand. In motion, it's pretty easy to see the wires bouncing around (from 1:26:13 to 1:26:21). (01:26:13)
Revealing mistake: When Red hits one of the demon bikers with his vehicle after he shoots it with an arrow, as the vehicle flips from the impact that there is actually nothing there he hit. (01:16:20)
Revealing mistake: When Velma sabotages the science project making it explode into purple goo, you can see that the vial of chemicals she tampered with simply spray around clean liquid, and the purple goo falls from above. (00:23:55)
Revealing mistake: When Asher is shooting a bolt-action sniper rifle there's no casing ejecting from the rifle as he reloads it with the bolt. (00:48:30 - 00:49:25)
Revealing mistake: When Poole arrives at the accident scene, both vehicles involved are in different positions. Kevin's SUV is partly in front of the Food Mart. Frank Lyga's car is about twice as far away from the SUV, the front is angled outward, and it isn't even close to the curb. Also, there are parking spaces to the right of the Mart, but not the handicapped parking that was there earlier. (00:19:26)
Revealing mistake: The tapered half of the baseball bat was leaning against the coffee table at about a 60° angle, but after Dave said, "The bat?" the camera showed it sticking straight up from (perpendicular to) the floor. Dave's lower body is then shown walking past the bat (which reaches to his waist) and stopping, at which point the bat fades into his leg until it is almost invisible. The next view of the bat shows it leaning against the coffee table again, but the coffee table is closer to the couch. (00:09:08)
Revealing mistake: Near the end when the orphans are exiting the building in the bus, you can tell they practised the sliding part. There are marks in the roof of the bus from previous takes.
Revealing mistake: After Jin beats up the two thugs with the pool cue, it cuts to Cheng walking down the street and on the phone. After getting off the phone, he continues walking, and some of the background extras can be seen looking at the camera as they walk past. (01:49:10)
Revealing mistake: After Jess leaned her bicycle against the pole, it slid down onto the ground. In subsequent views of the bicycle to Jess' side, the bicycle appeared to be upright and not what would be expected if it was lying on the ground. The height of the bicycle's seat should have been closer to the chair's arm, not Jess' shoulder. At a different angle before Jess got up, the bicycle was positioned like it was right after it slid onto the ground. (01:04:02 - 01:05:47)
Revealing mistake: When Scott is fighting Ghost, as Pym is planning to dive, Ghost throws Scott through a wall and you can see the braking cable around his/the stuntman's waist and across the floor. (01:16:48)
Revealing mistake: When the doctor with the satellite phone runs to the car, he is being chased by another member of the team, and of course the graboid. Look ahead of the graboid. The path it will take is visible.
Revealing mistake: The covering of snow was not real snow. When the trick-or-treaters are first seen, there are images of footprints (shoeprints) in the snow, but the trick-or-treaters walking over the "snow" do not leave any footprints. (00:44:38)
Revealing mistake: Eve says they need to make sure nobody gets shot, so she picks up Franklin's pistol and takes out the magazine to store them separately. However in this shot the magazine is completely empty with no bullets anyway. (00:53:40)
Revealing mistake: When the Wolf King is arriving through the elevator, there's a shot from a distance featuring Jodie Foster that wheels a chair in. You can see in it that the elevator arrow display is not moving; nobody is using them. (00:50:35)
Revealing mistake: When Paul Castellano is shot, there is a blood spurt shown from where the bullet hits, but the position of the gunman who fires at him doesn't match the direction the blood spurts. The gunman is across the street facing Castellano at an angle, but the blood spurt shown could only be achieved if the two were facing each other directly. (00:56:10)
Revealing mistake: Margaret's car and the way it was situated relative to already-parked cars in the courthouse lot was awkward. When she was sitting in the car, the driver's side-view mirror was angled outward yet gave a clear reflection of her face. The car in the row behind her was too close and at an angle, which would have likely blocked her approach. The car to her left was angled like a "V" to her car. These suggest/ indicate a green screen was used. Margaret's car appeared to be parked in the through lane. (00:53:58 - 00:56:52)
Revealing mistake: When Orm presents the weapons to Manta as a water hologram, Manta walks right through the hologram with half of his body. This arm passes through the hologram made of water and even makes a splash sound. However, there is not a single drop of water on Manta's completely dry clothing after this.
Revealing mistake: During the scenes with the cast on the bridge, there are clear traffic directing cones and lights visible in the distance, depending on the angle. This was done to prevent people and traffic from getting onto the closed set.
Suggested correction: Incorrect. They make a point of showing that there are "Bridge Closed" and construction signs on the bridge, and you can even see some construction equipment on the bridge itself. The cones and lights are not there to prevent people from getting onto set... they're part of the set dressing, since the bridge is meant to be closed down for construction in the scene. That's why they chose the bridge as a meetup point... there will be nobody to interfere.
