Idea for coursework

Film trailer:

The film is about a group of students who meet up in the woods, to celebrate one of their birthdays. They start drinking and messing around and one wonders off into the woods. The person doesn't come back and the group decide to split up in order to find him/her. They are eventually killed off one by one by a serial killer. Watch them fight for their survival as they try to avoid the horrors to come...

I am hoping to use Oxlea's Woods as the main setting of the film and a house to film the parts before the woods; the students getting ready to go out...
