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: 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?
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: 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.
Corrected entry: In one scene Mel Gibson is in his bedroom with a bathrobe on and bare legs. He hears his children talking and walks into their bedroom, again with bare legs. He walks into their room and sits on the bed to read their book. When he sits on the bed, he still has the bathrobe on but now also has jeans on.
Corrected entry: When Graham Hess (Mel Gibson) goes to meet his family for pizza, he sits down and they all stare at Ray Reddy (Shyamalan, in the red truck). As the camera pulls back out of the doorway, you can see that his slice of pizza is half eaten already, although he couldn't have been eating as he was staring at Reddy as he arrived.
Corrected entry: In the beginning of the movie, when Mel Gibson's family is standing in the middle of the crop circle, the camera zooms out and it looks like there are acres and acres of corn neatly planted. However, in other shots during the movie, you can see a bunch of trees growing all through the fields that weren't shown at the the very beginning.
Corrected entry: When Bo says, "Morgan took a sip and it has his amoebas in it," if you watch the film with subtitles the word is spelled amebas, without the o.
Corrected entry: When Graham and his family leave the basement, they find the aliens have carved holes in the wooden doors etc. If they could do this why didn't they cut through the wooden door to the basement?
Corrected entry: When Graham wakes up from the couch, he follows the cord into the closet to find his brother watching TV in the closet. However, you can see there is only one cable running from the living room to the closet: the power cable. To watch TV, you have to have two cables; the power cable for the TV and a coax cable from the wall jack which comes from the antenna or satellite dish or whatever. And I seriously doubt that they would conveniently have a coax jack in the coat closet.
Corrected entry: In the TV news footage where the alien is first seen (children's birthday party), the setting is supposedly South America. However, the children at the party are speaking continental Portugese (from Portugal), not Brazilian Portugese.
