After Rob saves Beth from her apartment, they work their way up the leaning building. When they reach the top and they are walking up the stairs to the roof, the stairs are perfectly horizontal even though the building is crooked. [Actually, when Beth and Rob are walking up the stairs, they are on the straight building, not the slanted building. They never walk up stairs on the slanted building.]

At about 18 minutes into the film when Rob, Jason and Hud are on the fire escape talking about Rob and Beth's relationship, Jason says, "You got to learn to say, 'Forget the world.'" But if you look closely at his mouth, you can see he says "Fuck" instead of "Forget". This was most likely censored to keep a PG-13 rating. [The DVD I watched last week uses the F word, not "forget."]

In the scene where you see some troops and tanks begin to attack the monster, you see one drive by Hud and it shoots its main gun. Problem is that the tank you see is actually an M109A6: it has to be stationary to fire its gun. Also, the blast would probably give Hud a concussion or make him go deaf. [The Howitzer's standard firing prodecure would be to lob shells on a distant target from a standing position. Given the current mayhem and close-quarters, the crew is doing whatever it can to take down the monster, so firing 'by eye', while not ideal, is better than doing nothing. As for Hud's hearing, he probably did suffer some damage, but given that he dies before the attack is over, we've no way to test how much.]

When Beth is at Rob's party, she has a gold top, but when they find her at her apartment, she has a plain white shirt on. [She's at her apartment, where you would think that a change of clothes would be freely available.]

In the scene when Lily tells Hud and Jason about Rob and Beth, the clock skips from 10 past to half past when the camera jumps. [This wasn't said, but the camera was either turned off or just not used for a few minutes at a time, probably to conserve the battery, explaining why it lasts all night, and the jump from the subway station to the middle of the subway tunnel. Lily told them not to tell anyone what she told them about Rob and Beth, Hud might have held out for about 20 minutes and not filmed any of the party for 20 minutes, then he started filming and told people.]

Just after the monster has capsized the oil tanker they go to the roof to check it out. When Hud says to Rob he should have left town earlier, Rob replies, "Shut up", however Rob's mouth doesn't move. [It does move, as does his head that turns his face into darkness so that the shadows across his face and the short time it takes to say 'shut up' under your breath all make it difficult to notice, but it's there in a completely natural way. It is not dubbed in.]

Beth's apartment slopes downwards, towards the window. This means that the building hers is leaning against should be visible. But it never is. [Beth's apartment faces Washington Circle, not the other building (as seen at the beginning). The tower of Time Warner Center that she lives in fell against the other tower. Her apartment is still facing the same direction, just tilted differently.]

This is a major plot hole. Whenever the camera gets dropped, scratched, etc. it does not show any signs of damage. In many scenes, such as when (SPOILER) Hud dies, the camera stays intact, even though it was just dropped some 30 feet. [It also survived a helicopter crash, but so did the three passengers. Just because it could be damaged, that doesn't mean it must be damaged. Many factors can be present that allow for the camera to remain working. Not impossible.]

When the Statue of Liberty's head lands and stops sliding accross the street, a street sign painted with 'dead end' is visible to the right. Any other shot after this, the sign is not there. [I can clearly see "D_AD DE_D" spray-painted on the back of the street sign as it's partially obscured by the pole. Perhaps it says "Dead Dead"? Regardless, the sign is seen while Hud is standing on the sidewalk just as the head settles into the street. Hud then walks into the street and all remaining shots are from the street so that the sign and pole are off screen to our right. The pole (but not the sign) is briefly seen as they are running into the store.]

When Rob is in the electronics store looking for a battery for his cellphone, he picks up a Nokia battery case so he can retrieve his messages. But as he ends the call the sound his cellphone makes is clearly one of a Motorola phone. (I sell both Nokia and Motorola cellphones which is why I know). [Cell phones allow the user to customize many of the features, including sounds. I know a guy that has a very expensive, advanced-looking, top-of-the-line phone that rings like an old desktop phone with a hard clanging metal bell (very cool). There's no reason Rob couldn't have installed the Nokia sounds out of preference for the sounds his previous phone made (familiarity/comfort).]

When we see the rebar stuck in Rob's girlfriend, you can see the rebar moving up and down with her breath. The only way to get it out of her was to lift her, so it wouldn't be doing that if they could have just pulled it. (The rebar was attached to the concrete behind her, otherwise lifting her would do nothing). [If you look closely, the rebar is attached to a piece of concrete, but the concrete isn't attached to the floor. Therefore, it potentially could move up and down with her breath (slightly of course), but they couldn't pull it up and out.]

The size of the creature keeps changing. When we see it from the roof of the Time Warner Center, it is almost as tall as the skyscrapers around it. When it steps over Grand Central Station, it is barely taller than the station. When it attacks the helicopter, it's huge again but (SPOILER) when it kills Hud, it is much smaller. This can't be explained by saying it's not in the same position every time, because it is always on four legs. The only time it's on two legs is when it reaches up to attack the helicopter and before that it was walking on four legs and when it was, it was huge. [Actually, it's not in the same positions each time. The articulation of its limbs allows it to stand quite tall or to skulk at a much lower level, as needed (see special features on DVD). The creature was, of course, computer designed and controlled, and it was automatically kept 'in scale' with the CGI city around it. Any perceived variances are caused by the limits of our 2D viewing of what should be a 3D scene. Our view is 'flat', so that all depth is lost, and distances between objects difficult to judge, and thus, our perception of scale can be distorted.]

The explosion in the city was impossible. The person correcting (my original mistake) watch close enough and notice that the explosion was IN the city, not the water where the oil tanker obviously was located (In fact we don't even see the oil tanker when the characters go on the roof). And the only sources in THAT PART of the city are the gas stations, and redial stores. [The cause of the first big explosion is never explained in the film, but then many oher things are not. Not knowing what DID cause it does not make it impossible. The Statue of Liberty's head landing on Manhattan is also not explained explicitly (but is obviously not caused by that first big blast). The capsized tanker is shown burning north of the Statue (meaning it also could not have caused the statue's head to land on Manhattan). And we don't see the tanker from the roof earlier because it's far away, hidden by buildings, and capsized at night.]

The shape of the creature's head keeps changing. When we first see its face, it has a large jaw and a human shaped head. When we see it at the end, its jaw is smaller, it has smaller teeth, its eyes have moved to the side of its head, and its head is more round. [If the creature is an alien. We have no idea of its specific biology, so even if the head does seem to change shape, there is every possibility that this could be a normal physical attribute to this kind of creature. a great many terrestrial creatures change their physical shape over the course of their lives. there is no reason an alien entity wouldn't be able to do the same thing in a much shorter period of time.]

The explosion in the city is impossible. The monster came from the sea, overturning the ship. Now the monster can destroy anything, but there is nothing in the city that can generate that kind of explosion launching debris over the river. Gas stations are the only thing in that part of the city and they cannot produce such a explosion. (It wasn't the military because nothing in the entire film apart from the ending killing the main characters was used. And yes we all know that there are a bunch of unknowns, but since this film really does show us the physical limts of the monster and the military, and the fact that nothing in the city - even power plants, of which there are none - could produce that explosion, makes this event a plot hole mistake.). [The cause of the first big explosion is never explained in the film, but then many oher things are not. Not knowing what DID cause it does not make it impossible. The Statue of Liberty's head landing on Manhattan is also not explained explicitly (but is obviously not caused by that first big blast). The capsized tanker is shown burning north of the Statue (meaning it also could not have caused the statue's head to land on Manhattan). And we don't see the tanker from the roof earlier because it's far away, hidden by buildings, and capsized at night.]

When we first see the military attack the monster, we see what appears to be an original M1 Abrams with the royal ordinace L68A1 105MM rifled gun. However, this tank has been out of service since 1987, replaced by the German Rhienmetall M256 L-44 120MM smoothbore cannon. Also in this scene, we see what appears to be an M109A6 paladin drive right past Hud, but this would never happen since an M109A6 is a self-propelled Howitzer and would fire from afar - it would never get that close to the target. [Just a few steps of this creature would place it far from where it was prior to those steps. As such, that Howitzer might have originally been at its proper range, and now is attempting to relocate. Also, Wikipedia notes 8000 M1s of various types are in current service, with 1000 of those being original M1 105mm models reported to likely be with the Army National Guard- the expected first responders in this film's situation.]

In addition to the creature's head changing shape, it changes size as well. When we see it from the roof of the Time Warner Center, it is half the size of the skyscrapers surrounding it. But when Rob, Beth, and Hud are running away from it, it is just barely taller than the house next to them. When it attacks the helicopter, it is huge again, but when it (SPOILER) kills Hud, it is much smaller. [The creature isn't in the same position every time -- sometimes it's on its hind legs, sometimes it's stooped on all fours -- which makes it difficult to gauge. But its size is consistent throughout the film.]

(SPOILER) The scene where Hud dies is a major plot hole. They are in the middle of the park. Hud drops the camera and come back to get it, only 10 feet away. Suddenly there is this gigantic monster, out of nowhere, right on top of him. It then kills him and drops him on the floor. Rob and Beth come to see him, and suddenly the monster is nowhere to be seen (or heard). It just vanished, giving them plenty of time to run and hide in the tunnel. How come the monster did not kill them? How come they didn't see it coming before Hud got the camera? [The gigantic monster takes gigantic steps as shown earlier in the movie, so it would only take the monster a few steps from far away to be on top of them. Rob, Beth and Hud are all rather preoccupied having just had a helicopter crash! And as for the monster vanishing, it too is preoccupied having just been bombed by a B2 bomber and isn't keen on hanging around.]

The Statue of Liberty's decapitated head is way too small to be accurate. Wikipedia lists the ear to ear width to be ten feet but it is just a little bigger than the compact cars on the street. [According the the FAQ on IMDb, the head shown is not unrealistic; it states "The head could easily fit on a city street, even on its side. The whole statue is only 151 feet high. The pedestal adds another 154 feet." It also adds further information relating to why the size of the head could be misconceived as being too small: "The makers of the film cited Escape from New York's poster as the inspiration for the Statue head scene in Cloverfield. However, that film's poster depicts the head as unrealistically large, which might account for the misconception that the head in Cloverfield is too small."]

After Hud, Marlena and the rest get met by the US Army, they are taken into a field hospital. It's later obvious that the US Army doctors and soldiers are all too well aware of what happens if someone has been bitten, therefore it's unlikely that the civilians would be allowed to mix in the hospital until checked out to ensure they were not infected. [We are never told what the military knows. And even if they did know, we don't know when they learned about it. We are not told how many bite victims they tried to treat before Marlena. The doctors could have just learned what happens to someone with a bite.]
