Continuity: Godzilla noticeably changes size throughout the movie. For example, he is shown lairing in a subway tunnel, but he cannot fit into the Hyde Park tunnel (taxicab scene), which is significantly larger than a subway tunnel. Also, compare the size of Godzilla's eye next to Matthew Broderick during the fish scene and Godzilla's death scene. The eye is way bigger in the latter.

Continuity: When the Mayor of New York is talking to the crowds and people can feel the ground bouncing, Godzilla is a fair bit away, but when he is stomping through the streets the people don't feel it at all - shouldn't they be thrown into the air from that proximity?

Continuity: Near the end of the movie there are 3 USAF planes.  The lead plane shows a graphic of 4 missiles, 2 of which he launches at Madison Square Garden. Then later, and without landing, the 3 planes fire at Godzilla.  2 missiles from each plane on both passes.   This means the lead plane fired 6 out of the 4 missiles.

Continuity: When the team is travelling to the cannery ship you see several people and a few vehicles going the other way. A helicopter flies over their heads and the camera shot from behind the chopper shows there is no one on the road heading away from the ship.

Factual error: The guys in BDU's (camouflage) have their sleeves rolled up with the lighter colored inside material showing. They are supposed to be Army soldiers. Only the Marines roll their sleeves this way. The rest of us can roll our sleeves up but have to fold the outer layer in a way that the darker camouflage material is still showing.

Continuity: During the scene right after the F-18's destroy Madison Square Garden, Godzilla goes after the taxi and Nick tells Phillipe to turn the car around. The problem is that on the street you can see that the first time they went through, Godzilla left some huge footprints and destroyed the street. When they turn around and drive up there a second time, the street is perfect. This happens again when they are stuck in the Hyde Park Tunnel and Godzilla shoves a claw into it and breaks up the road right in front of the taxi, but when Phillipe drives forward and then puts on the highbeams, the road is fine.

Continuity: When they are tracking the monsters movement towards the pile of fish, on a computer screen the icon representing Godzilla moves forward and in the next scene repeats over the same territory.

Plot hole: How did Godzilla deposit eggs in Madison Square Garden? It's obviously much too small for her to fit in. Almost all of the eggs are in the central dome, yet when our heroes are running around there is never any indication of a large hole Godzilla could reach through to place them inside.

Other: In Madison Square Garden, the French guy smashes Animal's camera, breaking it. When they are again being chased by the baby Godzilla's, Animal runs back to get his tape but leaves the broken camera on the ground. However, when they are being chased by Godzilla in the cab, Animal all of a sudden has another camera to film the chase. Where did he get this camera? When he packs his bag at the house, we see him put only one camera in there. Plus the bag is only big enough to fit one camera anyway.

Revealing: In the scene where they are climbing up from the subway tunnel into Madison Square Garden, there are lots of half-dead fish scattered around from when Godzilla was feeding. Right before they enter the arena, there is a high shot looking down on the actors, with a wiggling fish in the lower left portion of the screen. If you look closely, you can see a string attached to the fish. A crew member is obviously tugging on it from below, to make the fish move.

Other: When they are tracking Godzilla to the second pile of fish in Central Park, the tracking device says that Godzilla is moving with a speed of 175 mph. If you look at the shots before it with the soldier looking over the top of the building, it is impossible for him to walk at that speed.

Other: When the first fish trap is set up and Nick realises that the manhole covers need to come off, the first covers come off, with the pile of fish in the background about one block away. Nick then runs another 1/2 a block to a block to remove another manhole cover before Godzilla sticks his head up through the road. Taking into account Godzilla's size, we can assume he is about 3 blocks away from the fish. When the shot cuts to the computer screen in the command centre, it indicates that Godzilla is SIX blocks away from the fish.

Revealing: In the scene where they have the second fish trap, Godzilla runs from the army and the chasing hummers go right over footprints smoothly.

Revealing: When the old guy is running down the pier as Godzilla smashes through it it's very obvious that he was just cut in from a bluescreen. The water never touches him even though it gets passed him and he runs straight even though the pier shakes and bends right under his feet.

Factual error: Another CG versus physics problem: When the creature attacks the helicopters from the back, it eats one and the remaining two try to escape. However, the helicopters accelerate at least twice as fast as they would be able to in real life - they start from being still in air and they reach a circa 60kph speed in under two seconds.

Continuity: When the biologist guy has first contact with Godzilla, he signals to the soldiers that they should not shoot. How the soldiers can see from that far and in the heavy rain what his fingers are pointing is one question, the bigger problem is that when we see a close-up of the guy's fingers, there's no rain.

Other: At the taxi cab chase at the end, you can notice when the car is a real one and when it's CGI. Note how the real car has scratches and other things on the front of it, but the CGI car, if you look closely, has almost no imperfections, and even if it does have some, it doesn't match the real car one bit. You can see these things when the car drives off his mouth or when you see Godzilla running behind.

Continuity: When Godzilla is chasing the taxi, the taxi crashes through a chainlink fence. As it rounds the corner shortly after going through the fence, the sign on top of the cab comes loose and is being held loosely by a wire toward the front of the cab. You can clearly see that the sign is loose, but a few shots later, the sign is attached firmly in place atop the cab.

Continuity: As Godzilla is about to step on Animal, we see two cars are directly behind Animal (a yellow taxi and a gray car). Each shot of Animal from the front as the monster approaches (and he's trying to get the tape locked into the camera) shows portions of the cars. But in the side shot of the foot as it lands, no cars are right behind Animal at all.

Revealing: After the second attempt to capture Godzilla with the fish, she runs to the sea. You see her jump into the water, yet she makes a very small splash considering her mass.
