I am making a movie and I want to be able to develope some of my characters. But I want them to not be the normal shallow characters.

Jack Sparrow (whom everyone loves) is shallow. He has a quirkyness and these are charcteristics but are is it depth?

I want to know how to develope a character that has the quirkyness but also the depth.

Is there any advice?

I don't exactly what to tell you, but I'll give it a shot. For me, personally, if I want to write a non-shallow character, I start by thinking of a complex character arc. (i.e., values, emotions, methods, etc.) After I've established this, I can then add minor things to a character, such as quirk or wit, or whatever. I also find that using actual people as a source is excellent. I don't mean like obsessively watching a person, but take in consideration everything people do. Move, talk, respond, etc. Examine them carefully and you'll find that after so, writing a complex character will be that much better. I can't think of anything else. Maybe someone else will give you more.

Thanx a lot. That is valuable info!
