I search around on youtube.com for Blade Runner related material, and a wealth of clips was uncovered. Mostly user edited trailers and other simple creations, but still quite fun to explore. Here are some samples of what is available:

Another treat, found on Google Video, is the Channel 4 documentary “On the Edge of Blade Runner” from 2000. If you haven’t already seen it, I strongly recommend you allocate the next 52 minutes to watch it. It is also rumored that it’s going to be included in the upcoming SE DVD release.
