Corrected entry: Throughout the movie, the remaining Dog Isabelle can be heard barking when the Aliens are near or she detects hostility. However, in the scene where Graham sees the Alien on the Roof the Dog isn't heard - even when Graham and Merril are running round the outside of the house making noise and shouting.

Correction: Since it is never made known where the dog is during this scene, this can't be considered a plot hole.

Corrected entry: When the rest of the world finally starts seeing the lights in the sky, there is not any mention for the remainder of the movie of any military presence or actions being taken against the aliens. Given how simple the aliens are to defeat with water and physical violence this doesn't make sense, especially given the technology and weapons we have at our disposal.


Correction: The reason you don't see the military attack the aliens is because they do not yet know that the aliens are hostile. It is only after the aliens land and invade the Hess' home that it is known, by which point the movie is not showing the aliens in any other part of the world.

Corrected entry: When Merrill takes the bat from the wall Graham is standing not far from him. When the camera angle changes Graham has disappeared from the set. (01:32:35)


Correction: Graham is not standing far from him, but he's also not standing directly beside him. Graham had just rolled the television into the room, so he stands in front of that, near the edge of the doorway into the living room. The television (and therefore Graham) is simply out of the reverse angle.

Corrected entry: When Graham and Merrill board up the bedroom door there are some shots through the (closed) door. There is light on their faces coming from the left, where is only a wall and no light, as in all shots from behind. (01:11:15)


Correction: It is untrue that there is only a wall in that direction. There is a curio cabinet there. The light could be reflecting off the large pane of glass onto their faces.

JC Fernandez

Corrected entry: When Graham comes back home from Ray's house Merrill and the kids are sitting on the sofa. Morgan's book on aliens is lying on the coffee table on top of another, bigger book, first diagonal, then, when the camera angle changes, straight. (01:00:05)


Correction: In between the two shots is a lingering shot of Graham asking what the book says abot the aliens' intentions. Plenty of time for Morgan to have reached for the book, especially given that Graham is asking about it.

JC Fernandez

Corrected entry: When Merrill and Graham board up the door after they walk through it, Merrill bangs the nail into the board. If you watch his hammer, he misses the nail about six times. (01:10:45)

Correction: Happens all the time in real life, that's no movie mistake.

Corrected entry: Before the alien attacks Morgan in the basement, only Merrill and Graham have flashlights. Graham drops his flashlight as he goes to grab Morgan. Bo picks it up and shines it on Graham and Morgan, who are on the other side of the room; he then goes and sits with Merrill, putting both flashlights on the same side of the room. However, when Merrill says they should save the flashlights, one light turns off on either side of the room.

Correction: No. The flashlights are not only on the same side of the room, one is directly above the other. Merril turns off his flashlight first, then Bo, both on the left side of the screen.

JC Fernandez

Corrected entry: The dad walks into a room with glasses of water all over the place (this is after the night when the alien was on the roof) and his daughter is watching a cartoon, called "Dexter's laboratory". In the episode she's watching a scene is missing, in between the part where the father hits the bug off the ladies' hair and the part where the character says "do it up".

Correction: Content is often edited when episodes are rerun in syndication to allow for more commercial breaks.

JC Fernandez

This is generally not true of cartoons with short segments such as Dexter's Laboratory. Even if it were, Dexter's Laboratory has never been syndicated. Reruns are shown through Cartoon Network or the Cartoon Network owned Boomerang and they are never edited for additional commercial breaks. In addition it would not have been syndicated at the time the movie is set, as the film was released during the original run of Dexter's Laboratory in either the 4th or 5th season.


Corrected entry: In the scene where Graham hears Bo scream, he uses his right hand to open her bedroom door. In the shot from inside the room, his left arm is outstretched as if he had opened the door with that hand.

Correction: We don't actually see his left hand holding the doorknob. Being right-handed, it makes sense for him to use his right hand to open the door. But since the door swings leftward, he would use his left arm to nudge it further open.

JC Fernandez

Corrected entry: When the alien is killed in the end, we see his point-of-view as the glass of water tips and spills on his face, and you can blatantly tell that is a prop. Firstly, it doesn't spill as it tips, it only starts to spill after it has completly fallen over, which doesn't happen when a glass tips (try it yourself). And secondly, you can see it continue to pour out water for at least five or six seconds, meaning that more water has spilled than the glass could even carry.

Correction: We cannot see how full the glass is, so cannot say how far it would have to tip before the water poured out. Also, the filming effect showed not necessarily more water than it should, but slower than it should.

JC Fernandez

Corrected entry: When everyone is in the basement, Merrill breaks a light bulb while pulling an ax off a shelf. If you watch frame-by-frame, you will notice it breaks twice.

Correction: The rules of this site are very clear.if it requires slo-mo or freeze-frame it is NOT A MISTAKE.

Corrected entry: It is hinted that the aliens have been visiting Earth since the 1970s for recognisance purposes. In all that time, did they never notice how much it rains on this planet? Were the aliens flying over the deserts most of the time?

Correction: The info about how long aliens have been visiting Earth comes from the book Morgan and Bo are reading. This book is highly questionable as evidence, seeing how all of the information recited from it smacks of sensationalism, and a lot of it is completely false (like wearing tin foil on your head to avoid brain scans). It is therefore not certain that the reports on earlier visitiations are true. And even granting that they MAY have been true, according to an earlier correction it is possible that it is the contamination in tap water that is toxic to aliens, so observation of rain and clouds would not have revealed this danger to them.


Corrected entry: Late in the film you find out that water is to aliens as strong acid is to humans. However, earlier in the film when Mel Gibson goes to investigate the corn fields with the torch, the aliens are running around in the mist filled corn fields. Correct me if I'm wrong, but isn't mist just water vapor? Seeing how bad a glass of water ate away at the alien's flesh, even the slightest bit of water such as water vapour in the lungs and on the skin should cause serious damage or at least painful irritation, especially with prolonged exposure such as a few minutes. Just imagine a human breathing acid fumes, or walking in a room filled with acid gas.

Correction: It is never stated in the movie that water is what the aliens are "allergic" to. I think perhaps Bo's habit of stating that the water is "contaminated" is a hint. Maybe it's not water, per se, but TAP water that hurts them. There are lots of chemicals in tap water that don't hurt us, but could be toxic to the aliens.

That is incorrect, it is stated that the aliens have a weakness to water and that they avoided areas with large bodies of water because of that fact.


Corrected entry: At one point, the little girl turns up the volume on the television set, where some professor is discussing the crop circles. The television is muted, yet the sound comes on instantly when she presses the button. Furthermore, despite the fact the she has her hand on the volume button for a good few seconds, the sound level on the TV remains the same.

Correction: Not really a mistake as my TV works in exactly the same way. To turn it off mute I need to press the volume button. Also when i hold down my volume button it doesnt always turn the volume up. Sometimes there is a need to repress the button. This happens alot on older tv's or where the remote is not the original.

Corrected entry: Later in the movie we hear from the radio/TV that the aliens have been scared out of other countries as the inhabitants have discovered some "primitive methods" of defense. Of course its very unlikely that those countries wouldn't have mentioned the fact that it was water. Then it would only make sense to forward that information to the REST OF THE WORLD along with any newspieces. Is it that hard to say "oh by the way, you can rid yourself of any pesky aliens by using WATER.".

Correction: It's very common for news shows, especially here in the States, to bait the audience by introducing the most important and/or interesting information, then doing a commercial break: "Coming up next, what you don't know about the deadly chemicals in your own home." This is one such example. It's not extremely important to relay this information because for all intents and purposes the invasion is over - the alien ships have left and only a few wounded stragglers who should be quickly overwhelmed by recovering humans remain. The emergency broadcast about water as a weapon went out while our heroes were in the basement.


Corrected entry: These aliens are capable of interstellar travel, but they cannot figure out how to get out of a bathroom, with a wooden door and a simple lock?

Correction: Given their advanced technology they can travel across the stars. Without that, they're stuck with much the same physical equipment that humnas are. It would be easy enough to lock a person in a closet that has a deadbolt, even though humans are smart enough to figure out relativity.


Corrected entry: Ray tells Graham that he passed Graham's wife on the road 10-15 seconds before he hit her. How could he hit her if he already passed her on the road? What, did he do a U-turn in order to hit her?

Correction: Ray actually says that he just fell asleep for 10-15 seconds. During that time when he was asleep he hit Graham's wife.

No, Ray says, "after passing her." How do you run into someone you passed? If he nodded off, how did he even see her?

He noticed her on the road when he passed her the first time and hit her on his return trip.


Sorry but he most definitely said he passed her. When I heard him, I thought "what did he do, turn around and come back?"

He was making a relatively short trip in his car and she was taking a relatively long walk. He noticed her on the road when he was on his way to wherever he was headed and struck her on his return trip.


Corrected entry: When the family is eating the meal where they got to choose their own food they show a shot of Bo. She has a whole plate of spaghetti. After they show Mel Gibson eating, they go back to Bo and she has a half plate of spaghetti. (01:09:05)

Correction: Mel Gibson has taken some of Bo's spaghetti.

Corrected entry: Almost every time Morgan takes a puff from his inhaler, he doesn't depress the pump and therefore would not get any medicine. (00:10:05)

Correction: With the type of inhaler used, it is possible to activate it by a deep breath alone, thus negating the need to press it every time.

That is true for dry-powder inhalers, but Morgan uses a regular metered-dosage inhaler. That requires depressing the canister to get the medicine to come out. In addition, you can even hear a sound effect of the aerosol shooting the medicine out of the canister even though he hasn't actually pressed the canister down.


Corrected entry: I still can't get over how stupid the aliens are in this movie. If they are an advanced race that can travel through space, why are they naked and unarmed in their invasion? You'd think some weapons, armor or tools would help.

Correction: Morgan explains to Mel Gibson from his book that the aliens wouldn't bring weapons of their own because of the fear that man would eventually use nuclear weapons and therefore rendering the planet useless for them to use.

Continuity mistake: When Graham goes into Ray's kitchen you see the vegetables scattered and the knife further on the other side of them. When Graham leans up for the knife, however, it is on the other side of the now grouped vegetables. (00:56:40 - 00:58:10)

More quotes from Signs

Trivia: When the alien's hand comes out of the coal grate for Morgan, if you look closely you will see that the hand was already through the grate and the alien was using its colour changing abilities to hide. So if you look very closely you will that that the hand comes UP from the grate and not through it, and if you look VERY carefully you can see the outline of the hand even before Morgen says "What?"
