Revealing mistake: When Frank kicks the grocery store owner in the face twice his kicks miss by far.
Revealing mistake: When Cliff Booth is driving Rick's Cadillac, in some angles the speedometer is showing 0 (zero) as the car is driven down the boulevard.
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: When the Hårgas begin eating their meal after Dani is crowned May Queen, there is a shot of Dani just after the Hårgas pick up their knives and forks where she is looking over at Christian. Sitting next to her is a woman who cuts her food with a knife and fork, raises the fork to her mouth and takes a bite, but there is no food on the fork. She is just miming the actions. (02:13:15)
Revealing mistake: When Julie is talking to Stuart about her future, snow is falling in front of her. We can also see the wind is blowing, as it moves her hair. The snow, obviously CGI, is still falling straight down, and doesn't interact when the wind blows.
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: When Hamer goes to the gun store and obtains all of his weaponry, the gun counter guy and boy carry the weapons out to his vehicle. The weight of the weapons would be too much for one to carry all at the same time and the boy is supposedly carrying that large box of ammo, which would have contained over a thousand rounds, but he's carrying it like a box of feathers.
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: The sign with "everything must go" breaks a second before it hits Arthur. (00:02:55)
Suggested correction: The sign with "everything must go" breaks at the exact same second as it hits Arthur, and there is no point to make it somehow break by some weird special effect without any sense.
Revealing mistake: The film was rushed to theaters, leaving a few mistakes which Universal fixed. In the original cut, toward the end, Judi Dench's human hand is visible, complete with her wedding ring. This was fixed for the re-release.
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: Numerous times in the film the animals walk from shade into sunlight without their eyes reacting.
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: 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: 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: 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: 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 signal sweeps shown on the 'orca' device and on other screens throughout the movie are all identical.
Revealing mistake: The dead housekeeper's body is moving its hands like it's alive after it's unwrapped out of the carpet.
