ADDITION: 88 Films - Region 'B'- Blu-ray - March 17': The new Blu-ray is described as a "New 4K Transfer from the Original Techniscope Negative". The DVD, at 2.32:1, is cropped on the side and bottom edges. The 4K restored 1080P Blu-ray visuals are a giant leap beyond the 2002 SD. Colors are brighter, there is consistent, fine, grain texture visible, detail significantly rises and contrast is beautifully layered. The new HD is on a dual-layered disc with a max'ed out bitrate and, also, looks impressive in-motion.

Audio goes linear PCM tracks for both, the serviceable, English DUB and the original Italian (with optional English subtitles). There are plenty of effects - mostly aggressive violence - slaps, punches, screams and gunfire. The authentic uncompressed remains flat but is consistent with depth notable at times. The equally bombastic score is Umberto Smaila - his first film credit and it sounds solid in the uncompressed. The Blu-ray disc is region 'B'-locked.
