No technical specs seems to be listed on their website or on distributors' sites. However, I just found the following posting on the Criterionhttp://www.criterionforum.org/forum/viewtopic.php?f=5&t=9959 forums:
The Great Silence:
BONUSES: Interview with Alex Cox (Sid & Nancy, Repo Man), Alternate Ending (with optional commentary by Alex Cox), Theatrical Trailer.
Aspect Ratio: 1.66.1 Anamorphic
Format: Region 2 PAL
Language: Italian, English Dubbed, Optional English Subtitles
Running Time: 103 mins approx
What a wasted opportunity
My upgrade from the old UK release will definitely be the French release.
