" I am Legend" question?????????? *****SPOILER ALERT******************?

Did anyone wonder why the virus affected mice and dogs but not lions and deer. Or did you put any thought to how a bloodborne pathogen became airborne. How did New York become "ground zero"? Robert Neville says the zombie vampire dudes no longer have any human chareteristics, but they worked together and have pet dogs. Just a little food for thought. All in all I thought it was a great movie.

The electricity he got from gas power generators, they kept showing Honda generators throughout the movie, As for the water that would be tough, but I guess if he had a well and a power source he could keep water running as for a continuous source I don't know.

Well, since the virus itself is fictional, it's not unreasonable to attribute specific zoonotic characteristics to it. Likewise, since it's mentioned that dogs (and presumably the rats) are only vulnerable to the "contact" and not "airborne" variant of the virus, other animals could fall under the same catagory. Animals that exist as prey such as deer and those fierce and strong enough to ward off attackers in the wild such as lions and other large predators could in theory maintain populations free of the disease. On the other hand, dogs are social enough to congregate with infected humans yet not at the top of the food chain and would be vulnerable to attack and infection.

As for the water, I think we kind of have to suspend disbelief on that one. I don't think having a well in Manhattan is very likely and save for a civil engineer, I doubt too many people would know what would happen if nobody minded municipal water supplies.

my little brother just saw that movie, he thought it was pretty confusing too

I'm kind of curious how he still had running water and electricity.

Kind of made me wonder too.

Well its like lions. They hunt and kill but together they get quite along and dont eat each other like they do to others. The zombies in the movie are the same but Im not so sure about the pet dogs or the electricity...

Well I saw the movie and didnt let myself get distracted trying to rationalize things I just sat back and enjoyed the movie. Seriously how could a colnel in the U.S. Army afford a house like that in Manhattan now that is the biggest question of the movie.

Are you serious? I hate when people go to a MOVIE and then want a scientific explaination for the movies plot. even not seeing this version of the movie but seeing the other two here is probably how it goes. Just because the lions and deer are around doesn't mean that there aren't mutated lions and deer. animals reproduce faster than humans that is to say a woman that had an uninfected child on the first day of the outbreak and survived, her child would be only three years old , a child to us , where as a lion or deer who had a child on day one would have had three more children in that time and two of her children would have already had children. So you would see more survivor animals, beacuse their numbers would regenerate faster. plus rats and dogs are used in medical research so we must assume that in the inital testing they tested on rats and dogs, these rats and dogs probably infected other rats and dogs because the virus mutated to fit their genetic pattern, such is the nature of viruses.
new york is ground zero because the lab where they tested the virus is located in new york. If someone messed up protocol or stole the virus or whatever if it got out it would be the place where it was held.

Humanity and what make up human characteristics is all relative. They eat people thats not human and to him repulsive. So in his opinion they have no human characteristics. Plus in order to remain sane i think you'd have to seperate yourself from them. I'm Human. they are not. it's okay to kill and experiment on them. Otherwise how could you sleep at night.

as for the air borne thing. i assume its because if they thought about using this as a biological weapon, they would want a convient way to distribute this. Airbore is easiest and hardest to control. Everything breathes . So you change the virus and the delivery changes.

But whatever it's an action/sci-fi movie, there for your entertainment. you dont question how the holodecks work on star trek you just go with it. have an imagination.

the AIRBORNE VIRUS didn't affect dogs. only direct contact. Robert and Ana were both immune to both airborne and direct contact. maybe that's why the deer and lions weren't mutated.
new york was where it all started that is why it was "GROUND ZERO"
oh and animals also work together as a group.
hope i helped to answer at least 1 of your questions

No I didn't really wonder...it was clear in the movie that the virus affects people differently and animals differently.
New York was ground zero because that where the virus started...where they started using the vaccine.
As far as the human characteristics go...that was Robert's theory only.....a conclusion he came to before he found out that they could learn to set a trap for him just as he had done to them.................
