What was that spray?

Rating: 9/10 (9 October 2006)

I liked the movie. It was thoughtful and adventurous. It was done in a real-time basis that many people can relate to these days(how we get caught up in things like work, time management, etc). Question for movie buffs? what was spraying Chuck while he was on the wood raft? The first time it happened was at night - when he saw the whale. It happens twice more during the day - once when Wilson disappears and once when the ship passes. But it doesn't show what's causing it. Is it just normal ocean spray or is the whale back? Was the whale "helping" Chuck? if it was the whale, I think they should've revealed that fact more - it could've been a cool touch.
