12 monkeys; is it possible?

It was based on a new wave french film about the end of humanity as we know it but it raises question such as if its possible?
La Jetee's script can be found here http://www.godamongdirectors.com/scripts/lajette.shtml
The original movie La Jetee may only be 3o or so minutes long it is profound in it own way. Using only black and white film it features a number of stills to maximize the effects it has on people forcing you to become involved with in it.La Jetee is only so long but the fabulous director Terry Gillam, saw a movie that inspired him to create the film 12 monkeys. Nothing like this had been tackled before with both films talking of post apocalyptic world where we have become endangered ourself. i loved the way they captured the fear of possibility in its purest form. Nothing seems to out of their reach when they tackle the issues of a reality that may not even be real. The mind is only a fragile instrument and not only is it stretched to it limits it is torn into pieces. in the end only the true lie is the one we live. For nothing is common everything is different and only happens once within time.
