(Disclaimer: these are not my original ideas. I got them from my screenwriting textbooks; the titles to which evade me at the moment.)
So I have been doing a bit of screenplay writing lately (mostly just short films), and I have found that there is an interesting approach to character development in film that might be of service for your characters. It is a bit simpler than the Character Fractalling, so you don't get as much depth. However, it is a lot faster and can be done while you are writing. Thus you can get to know your character while you write, and then go back to make adjustments. Maybe you've heard of some of these techniques. Also, I would love to hear any other methods for approaching character development, so please feel free to discuss, disagree, ask questions, etc.
Basically, if you can answer the following questions for each of your characters in the story overall as well as for each scene, then you are well on your way to creating interesting characters. (Whenever I say "scene", just take that to mean a continuous flow of action with a distinct beginning, middle, and end. The word "chapter" doesn't work for this, because a chapter can contain many scenes depending on your writing style).
4 W's
What does the character want?
Why do they want it?
What's in the way?
What's at stake?
4 C's (to be used as indications of good rhythm for a scene or story)
Crisis
Conflict
Climax
Consequence
Luke from Star Wars is a good example:
4 W's (for the story over all, but you can/should do this for each scene)
What does the Luke want?
Luke wants to go off and have adventures with the Rebels.
Why does he want it?
Because he is discontent with life on Tatooine. Or because he wants to become a Jedi.
What's in the way?
He has no way off of the planet. His uncle won't let him leave.
What's at stake?
If Luke doesn't get off the planet, then he might be killed like his aunt and uncle. Also, Princess Lea will be killed, and the rebellion will fall apart.
(I'm not doing the best job at breaking this down, but hopefully you can get the idea).
4 C's (for a more specific part of the story)
Crisis
R2D2 runs away.
Conflict
Luke can't leave that night because of the sand people.
Climax
Luke and C3PO go out the next day to find R2D2 and get attacked by sand people.
Consequence
Luke is unconscious and C3PO is broken. (Don't worry, Obi-Wan shows up to save them in the next scene).
There is also Michael Hague's "Wound, Fear, Identity, Essence" (

Again, I just want to open up a discussion. I love working on interesting characters, and would love to hear anyone's thoughts on this. I personally found the fractalling system a bit too arduous to be of use to me personally since I like to find my characters within the framework of the story.
