NOTE: The below Blu-ray captures were taken directly from the Blu-ray disc.

Indicator transfer Jack Gold's unusual political, mystery, sci-fi, thriller film from 1974 Who? to a stacked Blu-ray package. It's on a dual-layered disc in 1080P with a max'ed out bitrate. The image is thick and very heavy which, I gather, is how the Kino 1080P looks. Textures overwhelm detail and colors seem to carry depth. It is in the original 1.85:1 aspect ratio and seems to export a consistent image quality throughout without noticeable blemishes. 

The audio is transferred ion a linear PCM mono track, in the original English, (24-bit). There are minor aggressive effects. The mono sound is decent supporting the score by John Cameron (Kes, Night Watch, 1988's Jack the Ripper, The Ruling Class). There are optional English (SDH) subtitles on this Region 'B' Blu-ray.

Indicator include the same 2010 audio commentary with director Jack Gold and film historian Tony Sloman. It's somewhat dry but has information about the production - locales etc. There is also a selected scene commentary from 2010 with actor Elliott Gould running just shy of 22-minutes filling in details like the make-up artist, Colin Arthur, who worked on 2001 etc. There is BEHP interview with Jack Gold from 1990 that runs to the full length of the film. It is an archival audio recording, made as part of the British Entertainment History Project, featuring the director in conversation with Norman Swallow and Alan Lawson. The Megaton Mind is an archival interview with actor Edward Grover also from 2010 running 25-minutes. The Man Behind the Mask is new and has 20-minutes of writer and critic Kim Newman exploring the life and career of acclaimed science-fiction author Algis Budrys. There is also an image gallery of original posters and book covers and the package contains a limited edition (3,000 copies) exclusive 36-page booklet with a new essay by Phelim O’Neill, an archival interview with director Jack Gold, a look at Algis Budrys’ source novel, an overview of contemporary critical responses, and film credits.

Who? incorporates a few different genres but is more a curiosity than a cohesive film effort. I kinda enjoyed it, but it isn't something I would strongly recommend although the extras on this Blu-ray were wonderful and the video quality probably accurate if underwhelming. Those curious may wish to indulge - the completeness of this BD package, with the extensive supplements, accentuates the value.
