I just got the US BD of Giorgio Moroders Metropolis Version. Some years ago I found the following website http://www.morodermetropolisdvd.com/ with a “fan made” redux Version of Giorgio Moroder’s Version. Sadly just avaible outside europe.
Has someon that disc, and could tell if its a well done edition? It seems to be a bit more colorised than the original Moroder Version.
