When you manage to express something with a look and the music instead of saying it with words or having the character speak, I think it's a more complete work.
Probably the greatest writer of westerns himself was Homer. His character were never all good or all bad. They're half and half, these characters, as all human beings are.
From Ennio [Morricone] I ask for themes that clothe my characters easily. He's never read a script of mine to compose the music, because many times he's composed the music before the script is ever written.
What I do is give Ennio Morricone suggestions and describe to him my characters, and then, quite often, he'll possibly write five themes for one character. And five themes for another. And then I'll take one piece of one of them and put it with a piece of another one for that character or take another theme from another character and move it into this character.... And when I have my characters finally dressed, then he composes.
I don't enter into particulars with [Ennio Morricone]. I give him the feeling and the suggestions of the characters.
