Research into genre

The film genre I am interested in doing is a film about zombies. However I want my zombie film to have a twist so I have decided to do some research and have decided that it would be good if I mixd it in with the railway children which has been both a book and later released as a film. Another reason that made me decide to do a zombie genre film is because it won't require as much budget as other genre's such as action.

In zombie films it always seems to start with a plague that starts to spread until it takes over the population of one place and then you have the hero's. The hero's always seem to do quite well at fighting back the zombies and then in most films one of the hero's will get bite and will also turn into a zombie.

Zombie films are usually filmed during the night to create a tension and so the film companies can make it more jumpy for the audience. However as the film goes on it normally gets lighter this connotes that the good is overcoming the bad and then its complete day light again and usually the zombies die.
