‘Gravity’ Extended Trailer Takes Your Breath Away [VIDEO]

I haven't paid much attention to what this movie is about (in theatres today) and figured it probably wasn't going to be something I'd be interested in.
That was before I saw this extended trailer on a rather large computer screen.
Wow, this is intense.
I don't know if I could handle watching this on say an  Imax screen in 3D, but I'm sure it's pretty awesome.
The real scary part of this movie is, it could really happen.
Check out the video, and if you see the movie, let me know what you thought.
