Something I didn't notice at all until someone brought it to my attention, the employee in the book store toward the beginning states to Morgan that a book accidentally came into storage. This is the UFO book Morgan buys that features their house in flames, with three bodies sprawled out in dead positions. Let alone the fact that the book never was suppose to come adds to the "sign", but what didn't don on me until my second viewing was that if Merrill had not "swung away" at the end, the three bodies sprawled out would have been Graham, Morgan and Bo, dead.

Before finding a few of the illogical facts surrounding the idea of the wife being an alien (for those interested), I had evidence backing it up through Shyamalan's bloody side, but also, on Graham's faith. His character is bare minimum on faith and refuses to owe another moment of his life to prayer. After my first viewing, I had thought that the gas had cured Morgan, which gave me a hint that it may have been the wife's way of inserting faith back into Graham's life. Another moment that hinted off at the hypothesis was that the critter at the end did not fight back at the encounter, which could have meant that they are not hostile. Merrill was not an evil person, which would have branched back to the roots of my first thought that they were ridding evil from earth. But through my second viewing, it was clear that they were hostile.

Although, if you think about it, Graham took a course of violent action against the alien in the pantry, which appears to be one of the few reasons why it shows up at the climax; in revenge. Would it be possible that the extra terrestrials were not hostile, but if you took a course of action against them, they would be? Though, at the very end, we see that there may very well have caused destruction across town. And thinking about it more, why would they kill the family dog near the climax? We don't physically see the dog attacking the aliens invading, but all we hear is the audio of the puppy being murdered. But it could be quite interpretative.

Some moviegoers may be confused as to why exactly the aliens got scared off at the very end and took off. Nothing is said right into our face about it, but you hear the brief moment on the television after the family heads out of the basement. Right before Graham unplugs the television from the closet there is a brief moment where the newscaster states that they've found a device to use in defense of the aliens, but it is not said at the time what the tactic is...for a reason. I didn't catch this till my third viewing. We learn from the final showdown that the critters can be killed by water, and if you put two and two together from that much, we can put together the fact that the aliens realized that water is their weakness and fled. But that one alien still had one case of business to finish before doing so.

Some have been asking about a possible flaw lurking within the basics of Signs. And that is, why would the aliens come to earth if the land is majority water when that factor is what kills them? If you remember back to the recruiting office, the over-the-top general character states to Merrill that they are "probing", which specifically refers to hiding in the shadows making sure it is safe "for the rest of them". The extra terrestrials were just checking our planet out and from the sounds of it, did not have knowledge that water was their weakness. Once they figured it out, they vanished in fear.

If you think about the themes of faith and fate within Signs, you will come down to the main theme of "everything happens for a reason". Without Graham's wife getting killed, they wouldn't have known to "swing away" at the very end which would have resulted in a high likelihood of death. So when you think about it, God killed off Graham's wife but the payoff could sit in the idea that one's better than four (deaths) and that fate brought Shyamalan's character into carelessly ending her life for a reason. Shyamalan subtly states in his car that the tragedy looked meant to be. So in a way, or really, the major point: good can result from even the worst events.

Outside of the secrets/meanings from Signs, you may very well catch M. Night Shyamalan's personal homage to Hitchcock in several occasions. First there is the shot of birds rapidly flying into the sky after Graham cuts the two fingers off the alien in a reference to The Birds. With the other being when (I think) Graham is trying to help Morgan through the asthma attack in the basement. There is a close-up of Gibson and we see his neck in a very good view. If you look intently enough, you will see the slight sketch of a bird; another homage to The Birds. And of course the opening credits is a basic reference to Hitchcock from the start, with a theme song that Shyamalan very likely took advice from Psycho.

For now, these are the facts that I could think up from Signs and if anything else comes apparent, I will add the scoop here. If you seem to think I'm missing something that is worthy of a mention, feel free to email me or use the form below.
