The woman who is washing laundry, puts it into a large metal bucket. The bucket has a large yellow handle on top. The woman puts the metal container in a wheelbarrow. The wheelbarrow also has a large wicker basket with no handle. When she turns the corner and then gets attacked by the zombie, the metal container is a different one, because the handle on top of the metal bucket has now completely changed. Also the large wicker basket now has an arched handle too.
In the end scene where the villagers have all of the zombies together in a barn and then set them on fire with a flamethrower, the scene starts in evening with the night getting really dark. But in shots you can see through the barns windows and doors, that the sky keeps alternating from dark evening, to bright day sky. Then after the zombies are killed by the fire, the sky has now changed to a permanent crystal blue day sky.
At the beginning of the film, we see the young woman fully dressed and carrying a bag with her, however six minutes in a gentleman asks a woman where she went stating that the young girl left her bag behind.
When the woman in the opening credits is taking off her clothes, she is about to take a blue pair of shorts from her bag, but decided against it. As she does, you can see a crew member aimlessly wandering around in the bushes behind her.
It's very obvious that all the "underwater" shots of the lake were shot in a swimming pool: during the first murder of the girl after the opening credits, you can even see an exit sign through the water. Near the end of the movie, as the Zombie are rising to the top, we can clearly see a bare pool wall.
