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?"

Trivia: When Graham Hess is reading the UFO book with his children in the bedroom, on the nearby table next to the lamp is a figurine of a soldier from the American War Of Independence. It is wearing the exact uniform as worn by Mel Gibson (Graham) in his film "The Patriot" (2000).

Trivia: The stories of the children's birth are actually the stories of M. Night Shaymalan's two children.

Trivia: M. Night Shyamalan originally wrote the characters of Graham Hess and Merrill Hess in their late sixties. The two young children were not Graham's children but his grandchildren. The role of Graham was offered and turned down by both Paul Newman and Clint Eastwood. When Mel Gibson expressed interested in the script, Shyamalan rewrote the Graham and Merrill characters to be younger and the two children were Graham's instead of his grandchildren.

Trivia: M. Night Shyamalan's scene in which he talks to Hess about the death of his wife was shot a day after a member of Shyamalan's family died.

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)

Question: First, let me say that the aliens being affected by only the "contaminants" in the tap water seems to be wrong. Two reason: 1)The Indian vet mentions that they don't like water, and 2) the aliens were avoiding areas with large bodies of water nearby. My question is this: wouldn't humans, who are over half water, be toxic to the aliens? Even if they processed the humans with different equipment and took precautions to avoid blood or body fluids, wouldn't carrying off a sweaty person burn the aliens? Seems like a dangerous harvest.

Answer: It could be that they are affected by the chlorine in the tap water (humans are affected by chlorine to, just look at Mustard Gas) to a greater extent then humans. The vet is only speculating about the landing sites. And while it is true that humans are mostly water, it is saline (i.e. salty like sweat) and has different chemical properties to pure H2O.

Well water does not contain chlorine.
