Man of Iron (1981)

Arrow 4K Blu-ray > Criterion 4K Blu-ray > Kino Lorber 4K Blu-ray see caps

Three masterings of the original Dolby Stereo SR mix exist: the original Orion video releases, the Criterion (which is from their LD) and the Arrow. All three are excellent with slight mastering differences between them. The original Orion still is probably the one with the most fidelity, the Criterion is the cleanest with a kind of warm feel to it and the Arrow has a bit of both aspects. The Arrow mastering has a tiny almost imperceptible bit of audio bleeding into the surround that isn't on the Criterion. Each has their own pluses and minuses but you can't go wrong with any of them. Whatever you do though: DO NOT WATCH WITH THE 5.1 REMIX. It is another MGM botch job that fundamentally alters the impact of many scenes. It is vastly inferior to the original mix in every way.

Criterion Blu-ray has exclusive extras, Arrow UHD has the most extras of any release

Shout! Factory's Blu-ray has both cuts of the film in addition to the 3.0 stereo and 2.0 mono mixes making it the first time the full theatrical cut is available with the 3.0 mix. The new commentary is good. The 3.0 stereo sounds wonderful and the mono sounds solid.
That's where the positives end. This is the same terrible Universal DVD master slapped on a Blu-ray disc with a terrible encode making both versions share the disc separately taking up more space. This master was already poor for DVD and is nearly unwatchable here on the Shout! Factory disc. It looks virtually identical to the upscaled DVD most of the time with only a bit less noise due to it being 1080p. This is one of the most appalling cases of "DVD master slapped on a Blu-ray disc" you can possibly find. Absolutely shameful video presentation. This should have never been released this way. Sadly it's still ever so slightly better than the DVD and the only way you get the proper theatrical cut with lossless 3.0 stereo. This is still the best source we have for the film.

This is an ancient Universal master of a film in dire need of restoration. This only looks somewhat better than the old Universal DVD upscaled and is clearly the same master. Tons of wear, color fringing and other issues abound. The film is stuck at the theatrical widescreen ratio of 1.85:1 when it was composed for Academy ratio. The proper ratio is only found on the trailer, original VHS master and Region 2 PAL DVD. The Kino Lorber Blu-ray is their usual barebones affair except for flawed low res trailer files and a basic commentary. The film's 3.0 stereo mix is intact alongside the more limited mono mix thankfully. The Blu-ray does edge out over the old Universal DVD but that is merely due to it being the same master resolving better in 1080p. This presentation is sadly poor and the film deserves much better.
