One thing Im not sure about though is whether or not Day of the dead is a proper sequel, are these people meant to be the same people who escape in a helicopter at the end of Dawn, or are they meant to be another group of people who also coincidentally escaped in a helicopter? (Maybe helicopter was the only way to stay alive, anyway Im not sure about this so email me if you have any theories). Also at the end of Day of the dead what actually happens? As the woman is getting into the helicopter she is grabbed and then suddenly awakes on the beach, does this mean the whole film was a dream or do you have to assume that they killed that zombie which attacked her and then flew to that island? If this is the case why didnt they simply film that scene where the zombie was killed and they made it to the island, it would have only taken a few minutes! (Email me if you have theories on this too!). Similarly is Dawn a TRUE sequel to Night or not, Is Dawn meant to be happening a few weeks after night occurs or not? One of my theories is that they are all happening during roughly the same time but follow completely different people unaware of each others existance. For instance, Night is the beginning of the zombie plague when they are still fresh and can run around and things. Then a few weeks later Dawn is near the middle of the Zombie plague where they are in the first stages of Zombiefication, ie, they are half human and half zombie, which explains why they still look human (sort of!) but walk around like zombies. Then Day of the dead is set a few months after Dawn, when the victims are now 100% Zombie (this explains why they look much more decayed than the dawn zombies) and are able to be more vicious and quick because they have adjusted to their new zombie body and are very hungry too (in Dawn food was plentiful whereas in Day food is very sparce).
