Often times, music is used to evoke an emotion and it's become a cliche, so I don't want to do that, and actually what I do, is that emotional intensity that has developed throughout the film, I allow it to get released by having that music at the end with the credits.
In fact, I had to make an enormous adjustment to this, not only in listening to it but in playing with it. It's a full sound. In some instances, you must have the volume to get the effect.
The corals do not look much worn, but still appear to have been dead. There are some delicate shells of molluscs from depths beyond 500 fathoms, where they were certainly living.
