Revealing mistake: When Gryffin first hears the animals talk to him, he runs home and at one point takes a bath. If you look at the bubbles, they move in a solid mass when he shifts around in the tub indicating they are not only fake but not real bubbles.
Revealing mistake: When Gosling overtakes the car via the shoulder, you can see dust in front of his Mustang being thrown up by the camera car.
Revealing mistake: There is a large rip on the side of Charge's mask. It is supposed to be that his mask has been ripped. But you can tell that the mask was designed to look like it was torn, the effects of sewing are obvious.
Revealing mistake: When the movie starts, there's an aerial view of London's rooftops. The smoke coming out of the very first chimney doesn't move, revealing it's a painting.
Revealing mistake: Whenever the astronauts are outside the module they are affected by being in a lower gravity environment. However, when inside there seems to be no effect, an example is when the helmet falls.
Revealing mistake: When Mater and Holley are talking in the corridor, Mater's reflection is cast on the wall, but Holley's reflection isn't. (00:29:55)
Revealing mistake: When Philip Seymour Hoffman gets a haircut, the camera is extremely close in on the electric razor going through his hair several times, but it is quite obvious that no hair is actually being cut.
Revealing mistake: When driving to the airport, you can see the reflection of street lights go over the front window, but the street lights out the back window never moves. (00:11:10)
Revealing mistake: We see a girl in a wheelchair missing her right leg, but we can briefly see her foot tucked under her left leg.
Revealing mistake: When she shoots the Ponzi scheme guy into his shark pool, the shot where he is seen from the side and sharks in the background, the shark can be seen in the glass part, but not in the water part between the man's arm and the glass piece. (00:58:50)
Revealing mistake: When the kids see the moon picture on the book, an old, chubby hand lays on the page, obviously not the kids'. When the angle changes, their small thin hands re-appear.
Revealing mistake: When Carter puts the dead guy in front of the thing that blows your tires, right before he runs over him, the dead guy blinks his eyes.
Suggested correction: The blinking is too obvious to be a mistake by the actor, the scene is supposed to show that the man was still alive after being stabbed, as a final bit of suffering. Terribly unrealistic in real life, but not for this franchise.
Revealing mistake: In the submarine, when Emma goes to get ice for Shaw, Azazel's tail is missing when he helps pull the submarine's ladder down.
Revealing mistake: When the cannibal throws Porter's body on the table you can plainly see its a rubber body. Especially when he cuts off the head.
Revealing mistake: After Eddie's big dive, as he resurfaces there is a reflection of the water that can be seen above the waterline (on the camera lens).
Revealing mistake: Near the end of the film when Jamie is 'talking on her phone' in the bathroom you can see in the mirror that she hasn't actually answered it.
Revealing mistake: When the LG billboard changes to the blue moon ad, the LG billboard is still visible on a reflection on the glass on the front of the MTV studios building.
Revealing mistake: Despite her claiming to be topless you can see what looks like a tube top on Kristen Wiig during her attempts to get the state cop to notice her.
Suggested correction: No, she's not wearing a tube-top. Looked up the scene on online. She has her hands covering her nipples, and her passenger Helen has her arm up in a gesturing manner partially covering her breasts, but there's absolutely no tube-top in sight. (I think you may be seeing part of Helen or Wiig's arm and think it's part of a tube-top).
Revealing mistake: As the guy is being pinned down by the giant hooks you can see for over a minute he can simply escape and slip his hands out. (00:52:30 - 00:53:30)
Revealing mistake: The gang is starting to argue as they are running behind schedule. The big guy is holding Nicole Kidman at knife-point. The camera zooms in on her breathing heavily...so heavily that the 'metal' blade of the knife bends up and down. (00:29:00)
