In this post-apocalyptic movie a family is stranded in rural Australia with the world overtaken by a violent pandemic that turns people into zombies within 48 hours. Despite being infected himself, the father desperately seeks a safe home for his son before he too changes.
In this clip the family are living on a houseboat and find themselves running out of food. Kay (Susie Porter), investigates an abandoned sailboat to see what she can find and is attacked by a zombie. It has all the hallmarks of classic cinematic build up. We know immediately that it's going to end badly when she looks at the sailboat. The filming inside is genuinely made claustrophobic, adding to danger. There is a slight reprieve when she happily finds a disposable razor. This is a common filmmaking trope; the subversion of the climax by a moment of anticlimax, only then to switch again to climax. Ultimately it is a well directed scene.
