The message behind Cast Away....
The message is that you never really know how life is, or how it's going to treat you until you are at your most desperate. The message is to live each day without the assumption there will be ice in your glass. None of us will ever know who we are or who we truly will be when faced with an actual challenge until we are out there. Between fishing for fresh crab, or contemplating hanging ourselves from the weak branch, we are all alone in our souls. The best we can do is to go out there and fight for survival, and fight for life.
