How long do you like to make a characters biography? I'm starting on a slasher screenplay and I was wondering how detailed do other writers get on their character bios for horror scripts like this one.
so the story should determine the characters not the other way around?
I may have misunderstood the question. I was referring to writing out a back story for each of my main characters before I start writing the screenplay. My thinking is that the better I know and understand my characters the more real they will be. I find myself thinking as the character while I'm writing so I speak in their voice and they come across more genuine and relate-able.
NEIL McCAULEY and a nurse get off. Neil carries a paper bag and wears white pants like a hospital attendant. Neil is an ice-cold professional: very big, very tough. At 42 his short black hair is graying. He spent eight years in McNeil and three in San Quentin. He got out and hit the street in 1987. Four of the McNeil years were spent in the hole. Neil's voice is street, but his language is precise like an engineer's. He's very careful and very good. Neil runs a professional crew that pulls down high line, high number scores and does it anyway the score has to be taken down: if on the prowl (a burglary), that's fine; if they have to go in strong (armed), that's fine too. And if you get in their way, that's got to be your problem. His lifestyle is obsessively functional. There's no steady woman or any encumbrance. Neil McCauley keeps it so there's nothing he couldn't walk from in 30 seconds flat.

I'd say if you're going to try out a character bio, just go for it. DOn't worry about length. Also, you can take an approach of answering certain questions about your character. What are his/her major ideas on major issues, on his/her own life? What major life events brought them to this line of thinking?
By the way, I think it's awesome that you are doing this for a slasher film. I am big fan of horror and the relatable characters really make the best movies. It's so much scarier/exciting to go through the dangerous series of events with a character you can actually care about. Just remember, if your protagonist is really going to be a fighter or a smart person trying to survive then your killer has to also be even more threatening and even more crafty than the average killer we see in film so we can appreciate just how special the main character is. Good luck!
