Revealing mistake: During the scene at the restaurant in Montenegro (actually filmed in the Czech Republic), you see a payphone with a Czech Telecom logo on it (itself a piece of history, as these are all now rebranded O2). (01:57:50)
Revealing mistake: In the disco scene, the DJ is playing music, but the Pioneer decks and the DJ Mixer are not even turned on, as no lights are showing.
Revealing mistake: When Pintel is running up to Ragetti during Elizabeth's rant on Isle Cruses, you can see the path in the sand where Pintel has run up in previous takes. (01:48:05)
Revealing mistake: In the first major battle between the 300 Spartans and the Persians, Leonidas is slaughtering the Persians and the speed of the scene goes from slow motion to fast motion, you see very realistic CGI blood. When the blood hits the the ground it suddenly disappears. This happens many times during this long and awesome scene.
Revealing mistake: In the scene in the laboratory under the mansion, when Wolverine confronts Jean about Cyclops, there is a close up shot of Wolverine's hand holding Cyclops' glasses. In this shot there is a small cut visible on Wolverine's hand - his healing power should not allow this.
Revealing mistake: In the park after the bad guys have been defeated and everyone starts returning to the museum, watch the T-Rex closely. In the overhead shot, he seemingly "floats" right through the branches of the trees which he normally would be moving. (01:34:50)
Revealing mistake: When the truck leaps off the ferry, the underside is seen, exposing the still-flaming 'roll cannon' opening in the rear floorboard. This cannon is what caused the rear of the truck to rise, sending the truck flipping through the air. (01:52:30)
Revealing mistake: When Alex sets-off the smoke bomb in the warehouse, the smoke is coming up from under the grate in the floor nowhere near the DS.
Revealing mistake: Watch closely when the first two 'slaves' run for their freedom amidst flying spears. When Jaguar Paw's friend (the chunky fellow) gets speared, it is a 'through the armpit' effect. When he's gasping for breath in the next shot, the entry of the spear is actually more in the middle of his chest.
Revealing mistake: In the scene where Tristan and Isolde have their first secret talk in the market, when the camera is on Isolde, you can see that she is wearing contacts.
Revealing mistake: Just before the end credits, as Superman is flying past Metropolis and into space, watch the car headlights in the background. The background shot is blatantly sped-up by a large amount, as all of the cars appear to be travelling at huge speeds, even in a traffic jam.
Revealing mistake: The money that the two gang members are counting in the opening view of the hotel room scene is obviously fake. Notice how white the bills are, when they should be greener and have more of the random anti-counterfeit features. (00:02:00)
Revealing mistake: In the helicopter chase Ethan and Lindsey (and the defibrillator) are just sitting on the floor of the helicopter while it is doing very radical moves. They would have been thrown around.
Revealing mistake: When Selene falls into the tunnels of Tanis's lair where the lycans are, you can see the pad she lands on. It's almost passed off as falling snow, but watch how as she lands the 'ground' squeezes like a pillow. This was pointed out in the director's commentary. (00:44:00)
Revealing mistake: When Jack drives the bus down the alley, it knocks a series of A/C units off a building. The last one comes open and there is obviously nothing inside. (01:12:35)
Revealing mistake: As one of the pilots opens a hatch to check on the failed "avionics" a side cockpit window is visible above and behind him. Rain on the window is moving directly downward, an impossibility at hundreds of miles per hour.
Revealing mistake: When Bobby is being chased by the police in his Dad's car it is blatantly obvious that a stunt double is driving.
Revealing mistake: Watch carefully after Angela is thrown through the windshield of the bus. There is a shot of diamonds and blood-stained glass scattering on the floor. But in reality, there is a shot of plain diamonds falling and the bloody glass is faded in during the middle of the shot. Most visible on the edges of the screen, where the pieces emerge from nowhere.
Revealing mistake: When the dragon is hatching, a light bulb is visible just behind and to the left of her egg. (00:14:10)
Suggested correction: What appears to be a light bulb in the wide shot is actually a leather strap attached to a larger leather item. This can be seen more easily in the close up shot in the moment after the egg fully breaks.
Revealing mistake: In the balcony in Havana, when Sonny and Isabella are talking about her old house, the shoreline view is not nearly similar to the real "Malecon" in Vedado, Havana.
