Different Openings of Films

We watched different genre films in class. Two of them we watched were Daddy Day Care and 28 weeks later.
Daddy Day Care started with an establishing shot of the house to show where we were. It goes in side and you see a young boy waking up to get ready for the day. Lively music is being played to make it more fun. He walks into the toilet and the music stops. You hear him goign for a wee and then the music starts again. This adds humour so we know its going to be a comedy.
In 28 weeks later, we see a family in a dark room. There are candles on certain people to show their importance. The mother worries about her children who went on a school trip and did not come back before they went into hiding. A disease had been going round and when people get bit by a dieseased person they become a zombie. All of a sudden there is a knock on the door. No one wants to let him in but they realise he is a small boy. The dad lets him in but soon after the zombies are at their house as they followed the boy their. Some of them get bitten and the mum, the dad and the young boy run upstairs. The dad goes to the window and opens it he calls the mum and son over but the zombie comes in so he jumps out the window and runs. There is then a running scene of him going to a river. There is a man with his boat. The zombies follow and he gets in the boat and rows off. We can tell from this opening that it is going to be a horror film where people are running from the zombies.
As a group we prefered the horror film so we chose horror as the genre of our own film.
