Factual error: In the first frontal shot of Percival's Porsche following Lorraine, virtually every car parked at the side of the road is from after 1989, one of them not even being on sale until 2007. (00:16:10)
Continuity mistake: When Pierce first begins to interrogate Caliban in the safe house in Mexico, a large portion of Caliban's albino makeup is smudged below his nose, revealing the actor's natural skin in his first close-up of the scene; after switching to a close-up of Pierce, then back to Caliban, the smudge has been fixed.
Continuity mistake: When Aquaman returns the sailor to the bar after saving him from the ocean, he drinks whiskey from a glass and notices parademon blood on his hand and the glass, in the next shot the glass is clean. (00:43:05)
Continuity mistake: Towards the end of the movie the main character is shot in the thigh. In the next scene (the end of the movie) the character is seen holding a wound to the stomach - his thigh wound having disappeared. (01:24:00 - 01:30:00)
Continuity mistake: Near the beginning of the movie, when the young adult Henry attempts to stop the British Captain from sailing into the triangle, Henry is subdued by the Marines. The British Captain accuses him of treason and rips both of Henry's sleeves down from the shoulders. The next camera view is from slightly further back as the British Captain commands the Marines to take Henry below and Henry's sleeves are still intact.
Revealing mistake: When the FBI agent is in the room of the court medic to get the cause of death, in several shots the sliced up corpse is breathing. (00:27:00 - 00:29:30)
Factual error: Throughout the whole movie, whenever federal agents (or people posing as such...) tasked with the case are shown, they wear uniforms with "U.S.A. Marshals" written in big yellow letters. Of course the one and only correct spelling would be "U.S. Marshal"
Continuity mistake: At the start of the song "Chillin' Like a Villain," Evie's shoes go from having high block heels to entirely different shorter wedge heels during the song. After the song, it's back to the high block heels. (00:38:20 - 00:39:40)
Continuity mistake: When the bald soldier gets into the cage of the apes, the amount of mud on his face changes between shots.
Continuity mistake: Laureline is not wearing a safety harness when talking to Valerian, but it appears and disappears several times as the shot cuts back and forth to Valerian. Laureline then puts on the safety harness she was already wearing.
Other mistake: To stop herself from bleeding after removing the tree branch from her body, Jen heats the wrapper of a beer can and places it against the wound. Later it is revealed that doing this resulted in the logo being branded onto her skin. However, if the wrapper was placed on her skin and the logo was facing towards her, then the logo should have been mirrored, but it's not. (00:57:40 - 01:05:20)
Continuity mistake: During the opening scene with Ego and Quill's mother, they run into the woods behind the Dairy Queen, and mom is wearing boots with fur trim. When they get to where the Ego's plant is in the ground, she is suddenly wearing sandals.
Other mistake: When Captain Underpants falls in the Turbo Toilet 2000's mouth which has a liquid in it, he doesn't turn into Mr. Krupp.
Audio problem: There are American crows (Corvus brachyrhynchos) calling in the distance during the initial pursuit for Quan in the forest behind the Belfast farmhouse, right after the trap door scene ends and we see two of Hennessy's men share a look. American crows do not exist in Ireland - only hooded crows, carrion crows, rooks, ravens and choughs.
Continuity mistake: When the Gunslinger rescues Jake in the forest, he fires far more shots than we see his gun is capable of holding when he reloads it.
Continuity mistake: At the beginning of the movie, Jamie Fox is stabbed. He goes to the men's room and the wound is on the right abdomen area as he applies the dressing to it. The rest of the movie shows him holding the left side of his abdomen area and the blood stains on his shirts also are also on the left side. (00:16:50 - 00:45:30)
Other mistake: Despite the up-to-date equipment used in the movie, Kate carries an old style film camera rather than a dslr. It was obviously so that she could develop the film later to realise her 'love'. At any rate, when going through her bag, she finds a roll of 35mm film to develop, but when the film is laid out on the light table for her to examine with a loupe, the film shown there is not 35mm. I think it was 126mm.
Continuity mistake: Batman plans to put the Joker in the phantom zone, and Barbara says no. She is still right in front of the SUV, but in the next shot, she is suddenly standing more forwards.
Continuity mistake: The car at the arresting scene was boosted by Baby a couple scenes earlier. When he gets arrested, he suddenly has a key of the car and turns off the engine. How did he acquire the key of that boosted car?
Suggested correction: We don't see him boost the car, though. He could have stolen it from somebody who was in the car, as he has done a couple times in the movie already.
Plot hole: After Rita kills Billy, why didn't any of the other rangers do something to help him? They could have very easily done CPR on him or at least called for an ambulance.
Suggested correction: (1) they did...they took him to Zordon. (2) These are high school kids. Have you ever seen any slasher flick before? Not every HS kid knows CPR.
Every high school lifeguard that ever existed.
Suggested correction: They may have not been in range with cellphone towers to get a good enough signal. Also, they had superpowers including super strength so doing CPR on Billy would have been very dangerous and would have probably hurt him even more.
