You can't tell any kind of a story without having some kind of a theme, something to say between the lines.
The Sand Pebbles has always been one of my favorite films, I suppose because its the most difficult film - from a physical and logistical standpoint - that I've ever made.
You look back on films sometimes and if they have not been as all-out successful as you anticipated you try to find reasons why maybe it didn't come off for audiences as well as you would have liked.
