Stumbling around the computer ( yeah, I'm addicted to this thing sometimes) , I happened upon this cool Entertainment feature on an MSN page.

Here is the link-  http://cadillacof.msn.com/entertainment/section.aspx?category=movies&topicid=5937761

They show a few such as Alien , 2001: A Space Odyssey , Blade Runner and others.

They are all great mentions, but one of my all time favs was The Day the Earth Stood Still from the 50's  and many more!

Tell me  a few of your own here, so we have an idea what Sci-Fi films are some of your best picks too.

Enjoy and I hope the FORCE is with you...........always.
