> Funny thing was that our local cable network showed the "extended version" (with the sentry turrets, scenes with Newt's parents, etc) and for years I thought I'd imagined some of those scenes because the extended version wasn't available on video until much later.

Wow. So there WERE sentry guns. For years (pre-Google years) I used to argue that there was a scene with sentry guns, though I don't think that's what I had called them. Those guns were awesome and they had made a huge impression on me. Problem was, no one else could remember seeing them. My family and friends swore I was crazy. So I asked for the uncut version of Aliens for Christmas one year (probably around 91 or 92) and I was so disappointed. No sentry guns. So I just figured everyone else was right. I must have imagined it or was mixing up my films. A few years later I purchased a "special edition extended version" on VHS which, sadly, also had no sentry guns. So that was that. I was wrong, there were no sentry guns, and that was the last I thought of it until now. I knew I saw those damn guns!
