in reply to GundarkHunter the DVD of blade runner i have is single sided that only has the directors cut on it (i'm in the UK though), but i couldn't find any original on amazon? or am i look in the wrong place. Also the recent film The Butterfly effect only has the directors cut on DVD here, does the region one have the original version as well?
Whilst looking i came across this
http://www.brmovie.com/BR_Special_Edition.htm
seems the directors cut is not the final version

But is my point about a directors cut/special edition replacing the original right?
