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.
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 can't tell any kind of a story without having some kind of a theme, something to say between the lines.
