Corrected entry: In the scene where the family are watching TV reports of other crop circles appearing around the world, the TV claims it's showing a picture of one in Wakefield, England. It is most unlikely that there would have been any crop circles in Wakefield, as there is very little arable farming near there. Most of the ones that did appear in real life in England were in the South.
Corrected entry: Early on, we find out that the reverend's wife was killed by a driver who fell asleep at the wheel. But the guy who killed her was still around throughout the movie. Don't you think that at least he would have his licence suspended or something? It seems a little strange to me that there were no repercussions for killing her at all.
Corrected entry: The aliens are obviously very intelligent creatures - after all, they mastered space travel, and presumably travel at or near light speed, in order to get to Earth. Considering that exposure to water is deadly, why would such intelligent creatures choose a planet which is three-quarters covered by water?
Corrected entry: When Morgan puts in the tape to record the news cast, he doesn't press record, or muck about doing anything you'd normally have to do when recording something.
Corrected entry: When Graham first sees the crop circles, he tells Morgan and Bo that they were too perfect to have been made by humans, but the rest of the movie he tells everyone it's just geeks with no lives doing it.
Corrected entry: In the scene where Graham, Merril, Bo and Morgan are eating the 'everything' dinner, in one shot, Bo's plate has half sauce and meatballs and the other half of the plate is noodles. A couple of shots later, her plate is again seen, but most of the noodles have been pushed back. She was to upset to be eating, so she wouldn't have moved them.
Corrected entry: It is revealed that the alien ships have some sort of cloaking device that prevents them from being seen to the naked eye. If they were that worried about being seen why not turn it on before they arrived over all the world's major cities, rather than letting the world film them, surely this would give them the element of surprise in the attack on Earth?
Corrected entry: The bat that Merrill uses to beat down the alien was his 507 foot homerun bat, but the bat appears in too good of condition to have ever been used in a single game, never mind smack a ball 507 feet.
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.".
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.
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.
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.
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.
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.
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?
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.
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.
