Sergio Corbucci’s Il grande silenzio aka the Great Silence seems to be coming to Blu-Ray (from German company Kinowelt) as it is now available for pre-order at Amazon.de under the title Leichen pflastern seinen Weg. Release date is 21st of October 2010.
Kinowelt’s earlier DVD releases of the Great Silence don’t have English audio or subtitles, but hopefully they can include them with the Blu-Ray.
EDIT: It seems the release date has been pushed back into February 2011. No idea why.
EDIT: And now the disc has no release date listed at Amazon.de. :s
