Corrected entry: In the street, Cassandra tries to catch some water in a rusty bottle on the pavement. After this you see a new can (blue-green-yellow with "N" sign on it) and then a rusty bottle again. (00:03:25)
Other mistake: They have a great electric fence, but the power goes out because of the storm. They all panic and flee the house, but the lights are still on in the house.
Question: When did Lt. Mark Hammond get the scar on his face?





Correction: Cassandra is so dehydrated and desperate for something to drink that she momentarily imagines the empty can being a soda can, but it becomes the can after she realises that there's nothing in it.
