Question: Do the individual aliens have cloaking abilities? It seemed at that the dogs were reacting to something that the people could not see. Were they smelling cloaked aliens? Were they going crazy to protect their human owners and that was misinterpreted as an attack on the people? I thought they are walking around at least invisible at times to do their work without detection. I may be wrong on that.
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.
Question: The director makes a point to show the audience the picture of Mel Gibson (in normal Catholic priest garb) and his family at the beginning of the movie. The question is, is Mel Gibson supposed to be a Catholic priest? Or is there another Christian denomination in which preacher's wear the same outfit that Catholic priests wear?
