Movies

Saw Inception, and it really got me thinking. Not that I need to jump off a bridge to wake up from a dream or anything crazy like that. Just, the depth of a movie like that. The reason it was so amazing, was because it was so "different" to us, so strange of a veiw on things. What kind of person is it that came up with something like that? What are his thoughts like? Does he think bizzare stuff like that radomly, or was he as surprised to come up with it, as we were to see it?
