That's right.

The main character in Secret Window, played by Johnny Depp, is schizophrenic. There are two sides of him.
So you can imagine why Hans Zimmer and James Newton Howard wanted to do this movie.
And so they did for Batman Begins, also a character with a dark and a white side.

It’s interesting when you consider that Hans Zimmer and James Newton Howard were originally going to collaborate on this, even before they knew they were going to be involved with Batman Begins

JNH mentions it in this article:

The last line’s particularly interesting-
"But Hans and I are we’re still planning on doing a collaborative score – we’ll find the right one!"

And they certainly did :)
