I've never watched this great and popular movie though I've heard a lot about it, I know it's very popular among the western folks, am also 101% sure many movies done in those ages has a little or more sublimal content in it, so I wasn't surprised reading this, but got enlightened the more about it.
Am sure I'll watch it one day, I hope they make a present remake of it like they did for Sound of Music and Beauty and the beast. So our generation could see it too.

Concerning the future prediction in the movie/book, many books actually Forsee all this things. Am a reader too, and I've seen and heard alot.

I just don't know the future could be this fast.
