Revealing mistake: When Five is walking back into the kitchen area of the yacht, one of the dead men with all the knives in him (closest to the camera) that she walks by slightly blinks his eyes. (01:53:34)
Revealing mistake: In the beginning of the movie, when Hellboy is speaking on the phone with "Dad", he's speaking on on speaker, but when the phone shows up, instead of showing a screen of a call on speaker with the duration on the call, the screen shows what would appear if he was receiving a phone call before accepting or declining. (03:35:00)
Revealing mistake: A major selling point of the movie is the CGI technology used to de-age Will Smith. The effect works for the most part of the movie, including scenes in daylight, but in the last handful of minutes, maybe because of the plain 'happy-ending' light used, maybe for budget reasons, the face of Junior is thoroughly unconvincing, with a dramatic drop in quality in textures and modelization. (01:44:30)
Revealing mistake: During the electric shock scenes, the chairs are made of metal and hooked up to Jeep batteries. Hobbs and Shaw then proceed to smash the chairs up in the ensuing fight scene. Only for them to reappear just as the bomb goes off destroying the plant. (01:12:50 - 01:15:25)
Revealing mistake: On the way to the border, after Gabrielle has died, when the camera pans it on her face, you can see her eyelids shift and blink.
Revealing mistake: When Dane throws the blade back at Nix he severs two of her fingers, along with the skull ring, from her right hand. A short while later, when Nix grabs a hammer and raises her right hand while shouting, "I have the power," there's a nice closeup showing all five of Nix's fingers gripping the handle. (01:14:05 - 01:15:45)
Revealing mistake: During the escape after the crippling of Berrada, there's a sequence where one of Sofia's dogs gets under her legs and she pets him briefly before launching him to attack one of the bad guys biting him exactly in the crotch. She then shoots him twice in the face putting him out of his misery. Under the person's shirt you can see the squared profile of protective padding. (01:00:00)
Revealing mistake: At the start when they're clearing the White House field Little Rock shoots her gun without her finger on the trigger. (00:04:20)
Revealing mistake: After the Kree arrive on the ship, in a side shot one of them opens the lunchbox holding the tesseract. We see the blue light emanating from inside, but that only appears once the box is fully open - while it's opening, there's no light inside at all, despite the tesseract always glowing. A later shot shows the glow being visible around the edges of the lid even when the box is completely shut, and when Carol opens it later, the glow appears immediately.
Revealing mistake: Mazhar is saved by Raghu who with his amazing strength pulls the chains tied to the tankers and breaks free. The chains supposedly pulled by the powerful trucks though are not in tension. (00:08:50)
Revealing mistake: The helmets the soldiers are wearing are made for airsoft/paintball players. No military would issue soldiers with helmets that had holes in them for field duty, as that could allow bullets or shrapnel to penetrate the soldiers' skulls.
Revealing mistake: The dead housekeeper's body is moving its hands like it's alive after it's unwrapped out of the carpet.
Revealing mistake: The signal sweeps shown on the 'orca' device and on other screens throughout the movie are all identical.
Revealing mistake: She is driving and puts her phone down, you can see that car shifter is in park instead of drive.
Revealing mistake: A lot of the CGI was quite good and, even if not totally realistic, was interesting and exciting to watch. However, the man supposedly rappelling (or abseiling) down the mountainside was obviously not there - his feet didn't touch the mountain. (00:36:10)
Revealing mistake: After most of the people trying to hang onto other people holding onto the ascending helicopter fell off, a downward view from the helicopter showed a man effortlessly hanging onto the landing skid and a woman just as effortlessly grasping his jacket's shoulder. (00:02:50)
Revealing mistake: Obvious use of green screen for buildings across the street. On and off, the background fades, and buildings appear higher or lower depending on the camera's angle. At one point, the angle of walls behind Rex (Bruce Willis) is at a downward angle, and his head is almost touching the ceiling. (00:06:10 - 00:07:25)
Revealing mistake: When Shaft thinks about the address of the drug supplier, he stares at a newspaper clipping on the wall. The clipping is zoomed in close for over 1 second, and it's more than enough to spot the famous words "Lorem ipsum..." at the beginning of the article, revealing the clip to be just a movie prop with the industry standard filler text jibberish. (00:27:10)
Revealing mistake: In Guatemala, when Arnie shoots John, in the shots from behind Arnie's body double is noticeable.
Revealing mistake: Ron leans against a barrel and sets in motion a series of events leading to an explosion. For being able to tip it with such a modest push, it is obvious it was empty (confirmed also by how it bounces). (00:02:20)
