I found out by reading some post in the alt.fan.blade-runner newsgroup that the fantastic Channel 4 Blade Runner documentury “On the edge of Blade Runner” (Which is said to be included in the yet to be released Special Edition DVD of Blade Runner) is available at Google Video for anyone to watch.
So head on over to Google video and the On the Edge of Blade Runner documentury now and enjoy a great documentury which contains both Special Effects video and videos containing “the story behind the story” with Philip K. Dick and the lost “Hospital Scene”..
If you somehow want to find out more on the documentury, check out Los Angeles, 2019’s own On The Edge Of Blade Runner page.
