Other mistake: Tony Danza's character introduces himself as "Tony." When the credits are rolling at the end of the movie, we see that his character's name is Terry, not Tony.
Other mistake: When we see the numbers for the coded entry to Alice's weapon, the order of the numbers is 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 0 - 9. The 9 and 0 are the wrong way round. (00:47:40)
Other mistake: Scott Lang is swept out of the tub after having shrunk for the first time. When he lands on the ceramic bathroom floor, falling roughly two feet, there is an audible glass breaking sound and it appears he has broken the flooring with his fall. He then falls through a plaster ceiling to free fall down to a turn table, landing on a plastic vinyl record played by a DJ. The album does not break despite him having fallen from three times the height and landing on a weaker material. Moments later, he is thrown through a second storey window and lands on a car in the street and his weight is now once again sufficient to form a small dent in the hood. (00:31:15)
Other mistake: The Tiger tank wouldn't have burst from cover after picking off one Sherman. Why would it when it could stay put and pick them off as they approach? Even in 1945 when recruits weren't always well trained, the German Wehrmacht didn't give Tigers to newbies. (01:17:10)
Other mistake: The driver tells his partner that his firearm is empty, and he has no bullets in it. In the beginning he was given a loaner firearm until he could purchase his own. He's been with the company for a while now so that makes no sense. Also, for a trained professional who killed six robbers with precise accuracy it's hard to fathom he would not notice his gun weighing less. A loaded Glock 17 weighs 8.5 ounces heavier than an empty one. Plus the guards carry spare magazines, where are his? (01:20:00 - 01:22:30)
Other mistake: Major Turner tells Reacher that the men Parasource killed were shot twice in the back of the head. During Prudhomme's telling the images show the downed soldier on his back. The other is shown being shot and falling on her back. Then the two kill shots each. They couldn't have been in the back of their heads.
Other mistake: At the end of the movie where they are looking at the headstone of Jake Hobart, the date on the bottom of the stone is April 3 1913, despite dying shortly before the Titanic sank in 1912.
Other mistake: When Batman is video calling the Riddler and passes the phone over to the D/A, you can see Batman's face still looking at the phone in the reflection of the Riddler's glasses.
Other mistake: When Memphis and Kip are hiding from Johnny B and his crew in the cafe following the ambush, Memphis devises a plan to make good an escape. He sends Kip out to use the tow cable on the heavy tow rig to destroy Johnny B's Mercedes. First angle shows a cable wrapped around a rear A-arm of the vehicle and the hook connected to the cable, the next shows a hook directly attached to the front axle, which is the one that gets torn from the Mercedes when the tow rig pulls away. Additionally, a different cabling rig and loose cabling used in the stunt are strewn behind the car. So even if Kip somehow made 2 connections without being seen or heard, the rear rig is different than the one shown in the first shot. (00:51:00 - 00:53:00)
Other mistake: When Ethan shoots gas at the black SUV where the Italian accountant is, the two bodyguards faint instantly, Ethan wears a mask to avoid that, but the accountant never faints, and keeps awake and screaming all the time.
Other mistake: When Tsireya is shown swimming with Aonung and Rotxo, her right shoulder strap is glitching through her shoulder. It then proceeds to slip back out of her shoulder and into its correct place. (00:59:10)
Other mistake: When Dean compliments Les on the great driving making up for a year of boredom, Les looks around up in the air in a direction away from the car, then suddenly says "there's a scratch on my car." He then looks down on the car at the scratch and shows Dean. He said the "scratch" line before actually seeing it.
Other mistake: During the mine scene, we see Stacy Sutton in very tight miner's overalls. Then, Mayday rips them off to reveal the white dress she was wearing beforehand. There was not enough room in those tight overalls to hike up or bunch the skirt in any way for her to move her legs or have both legs in both pant legs. (01:47:05)
Other mistake: Throughout the entire chase scene at the end, the vault creates sparks on the road. Yet when they get to the bridge, no sparks appear. This cannot be due to the vault being empty at this point, as the vault itself is 10 tonnes, as mentioned earlier in the film. (01:49:00)
Other mistake: When Robert Downey Jr. lowers the helicopter onto the freeway to yell at the truck driver, he is very close to the truck driver, so close that the truck driver can even hit the helicopter. Why does a long haired man standing underneath a helicopter not have his hair blown around?
Other mistake: At the taxi cab chase at the end, you can notice when the car is a real one and when it's CGI. Note how the real car has scratches and other things on the front of it, but the CGI car, if you look closely, has almost no imperfections, and even if it does have some, it doesn't match the real car one bit. You can see these things when the car drives off his mouth or when you see Godzilla running behind.
Other mistake: On his own computer, Sean looks up his son's file, which states the boy died immediately and his date of death was September 9th, 1991. When Eve and Castor (as Sean Archer) are at the cemetery, the date of death on the headstone is September 24th, 1991. (00:21:15 - 01:14:50)
Other mistake: The guy says "looks like I'll have to send more flowers" then opens up the activation card and code to destroy the building. The code is 50617 but he swipes the card then pushes 50671. (01:00:00)
Suggested correction: If you watch the keys again he presses the exact appropriate numbers in order. 50617.
Other mistake: During the pub fight scene, the guy who got hit with the glass cup (Wound on his forehead), pulls a six shooter out of his pants, but he fires eight bullets at Harry's umbrella.
Other mistake: After the veterinarian throws blood all over the floor, we see clean spots appear on the floor in the shape of Sebastian's feet as he walks through the blood. Somehow he never has any of it stick to the bottom of his feet (even when he's in the puddle).
