The “zombies” in the 2008 John Dowdle film Quarantine come from the, “we were infected by a super-rabies and are now rage-filled killing machine” stock, but it is still an example of what happens when you lock people in a building with blood-thirsty killing machines who consume and infect the living.
Interestingly enough, other than being a fairly compelling film shot in “first person” with the audience seeing the action through the eyes of a camera-man, it also holds the distinction of being one of the few films that have put the final scene of the movie in the trailer as well as on the poster.
Not that there is too much question as to what is going to happen.
The plot goes something like this. There is an outbreak of some kind of super-rabies in an apartment building. Emergency personnel are sent in to investigate. The government decides that it would be in everyone’s best interest if none of the people inside the building (including the emergency folks) got out alive. You have to contain the infection, right?
The rest is a fairly classic romp through the killing fields.
The lesson we should draw from this is that the only point of nightvision when you are being attacked by evil, rage-filled creatures is to give you 3 seconds of illumination immediately before you have your face eaten.
