Hearts of Darkness: A Filmmaker's Apocalypse 4K UHD (1991) (StudioCanal)

[McCrutchy]

To be fair, the theatrical cut of Apocalypse Now is still available fairly easily. Ideally, there should be a "budget" version available with both 4K UHD discs, but you can get, for example, this four-disc German release:



Which has the two 4K UHD discs for the three versions of the film and the two Blu-rays of extras (apparently region free) while dropping the redundant Blu-rays.

In fact, the German release looks to have TrueHD 5.1 for the theatrical and Redux versions, but I don't know if that's just a downmix from the Atmos remix that's on the US, UK and Australian editions.
