I'm not sure if this is supposed to be in here or the Screenwriting section so if it's in the wrong section, please move to correct section. I tried asking on Google but with no avail. Maybe I'm phrasing the question wrong. Before you start writing the screenplay, you have to start planning the ideas and whatnot. I was wondering about the story part. Whether you're writing a short or a full length feature, how long should your story be before you actually start writing your screenplay? This has been bothering a bit. I have the basic premise as far as character bios to how I want the story to unfold but I'm just unsure on how long the story has to be or is there no rules to this?
