I watched "Cast Away" with Tom Hanks again recently, and saw a lot of interesting things in it.
The biggest is the very obvious sort of catastrophic, life-changing ordeal that strips away all of who he THINKS he is, forcing him to abandon his previous life. While many people see this happening to him by something other than his choice, in fact, it IS his choices that lead him to this place, even if he doesn't consciously know this.
Another thing is Wilson the Volleyball. From a solipsistic point of view, or, indeed, from some kinds of experiences of non-duality, Wilson is a really good example of what Source has done in creating us. Wilson is not actually animate, nor is Wilson actually real. It's all in the mind of Wilson's "creator", who comes to love him and depend on him for company. We're all volleyballs in the sense that we are not animate on our own, but are only animated by Source...
Also the place where the main character finally just surrenders, and it is only at that point that he finally gets what he was seeking. Interesting.
I'm not sure if the screenwriter and/or director really fully appreciated the potential spiritual aspects of the film, but I like looking for these things, even if they're not in there on purpose or by conscious understanding of the filmmakers. Art isn't just what the artist makes, but what the viewer makes of it in their own experience.
