A little competition?
I need an antagonist—male or female doesn't really matter. I'm shooting a horror film. It's supposed to be about a class that's supposed to work on a project. It should be understandable why the antagonist became a killer. I need a strong character.
If you have any ideas for a protagonist, please feel free to mention them.
What project? What class?
As a basic framework, this is quite weak. What’s your location? What kind of students are there? In what time and in which culture should your film act?
For a credible character, it also needs a coherent plot.
