So I just got the four disc collectors editions of "Blade Runner" and have never seen the film. I am at a bit of a lose of how to proceed. I don't know what version I should watch first and really have no idea about how they vary.

The available options are:

The Final Cut (2007)
U.S. Theatrical Cut (1982)
International Theatrical Cut (1982)
Director's Cut (1992)

So what order should I proceed in?

Thanks in advance.

If you're planning on watching all of them then the order probably doesn't matter, otherwise I'd go for the Final Cut. It's the only version that Scott had complete control over and I generally like the changes made from the Director's Cut, while the Thteatrical Cut would best be avoided all together (IMO).
