Factual error: At the beginning of the movie when Danny Glover is sitting at the chessboard, the pieces are lined up wrong on both sides of the board. If Danny has the white pieces, the king should be on his right. The black king should be on the opponent's left.
Character mistake: In his opening prologue, Burt says the Graboids have been contained to the Northern Hemisphere, showing a map highlighting the Graboid attacks of the first film in Nevada and the second film in Mexico. However, it overlooks the Graboid/Shrieker attack in Argentina, in the Southern hemisphere, shown at the beginning of Tremors 3, an incursion Burt personally put down. It's not like it was classified - characters in that movie talk about it being reported by CNN, and characters in the Tremors TV series talk about it as well. And it's not like Tremors 3 is no longer canon, since Burt makes two references to being swallowed by the Graboid in that movie (which also becomes a plot point in Tremors 6).
Continuity mistake: As Jake and Olivia steal a car while their enemies are shooting at them, we see a rear-view mirror. A few seconds later, Jake turns to check if they are followed, and the mirror has vanished. As they reach the safe house the mirror is back. (00:19:55 - 00:21:30)
Factual error: Although this 2015 Norwegian disaster film is far superior to the many American disaster movies that it emulates, "The Wave" still suffers the most common error found in tsunami-themed disaster flicks: Crystal-clear flood waters. Of course, tsunami flood waters in particular are always inky-black with churning sediment and debris.
Continuity mistake: In order for Superman, Wonder Woman and Batman to break into the secret room, they knock it down. Four enemies who were waiting for them in front of the door are crushed by the falling door and blood is splattered, forming a pool of blood in front of the door. During the fight that follows, there are several shots where the knocked over door is shown, but the pool of blood at the front of the door has vanished. (00:07:10)
Continuity mistake: As Sean Penn arrives in the bar at the beginning of the movie, Annie is engaged in conversation with another man, saying "We have to meet the new Minister of Health." You can spot her in the group shot and she has her elbow on the table and leaning her head against the hand. In the close-up her position is completely different. (00:03:00)
Revealing mistake: The group ambushes a German patrol with a half track and a tank. After the fight is over Dolph sits on the ground leaning to the tracks of the tank. The Lieutenant comes back alone holding his Thompson submachine gun. You can see that the barrel is plugged with an aluminum insert to enable the operation of blank cartridges. (01:00:00)
Factual error: In the fighting scene in U-Bahnhof Alexanderplatz the underground trains move much faster than in real world. Alexanderplatz is a railhead station. The trains would either crash into a wall or would not have enough room to accelerate that fast.
Continuity mistake: Emily's bra disappears at the gas station and her sunglasses come and go.
Continuity mistake: During the fight in the garage, the protagonist neutralizes (and maybe neuters) one of the baddies crotching him with the car door. In that sequence, his hands keep changing position on the door. (00:07:30)
Continuity mistake: In the scene with the fireworks, the Deputy driving the vehicle has his outside mirror knocked off by a firework. You then see the same and only Deputy in the car, in the mirror getting out of the passenger side of the vehicle to confront the misfits. The change isn't due to the reflected image. (00:13:05)
Continuity mistake: The drawing of the church Kelly shows is different than the one she started to draw, even if she erased lines. The whole thing is shifted over to the right and both top lines go from angling towards the horizon to one being straight.
Continuity mistake: At the very start of the movie as the 2 guys walk down the alley way, the one in the black jacket lifts his arm up as he passes the rubbish bin. In the next shot from the front both his arms are in his pockets and the rubbish bins completely disappear. (01:00:00 - 01:01:00)
Visible crew/equipment: When Matthew is following Nina's cries for help through the woods you can see numerous set lights in between the trees (in the distance). (01:09:43)
Plot hole: Echelon controlled satellites hit targets on Earth with pinpoint accuracy. A lot of them involve creating storms to ravage an objective. One of them is started over 18 hours away from the target (how they know is another mystery), but this is what gives the characters time and allows the movie plot to continue to the end to defeat Echelon.
Continuity mistake: During the saloon heist, Luke Wilson comes in to distracts Harvey Keitel. Danny pulls out a roll of banknotes to buy "some real scotch from Scotchland"; one of the girls poured a drink to Smiley and put the bottle down, but the bottle in a following shot is in a different position. (00:50:50)
