A Blade in the Dark (1983)

Included in the Complete Kubrick box set with FiM encode of the same master from the WB release without the filtering, 1.85 ratio restored for US Cut; both US and International Cuts are 4K.

No Blu-ray or DVD release until the Criterion 4K Blu-ray has presented the US in its original theatrical aspect ratio of 1.85:1. The International Cut has never been presented in it's OAR of 1.66:1 in any home video releases.

The packaging on the back of the WB 4K Blu-ray incorrectly states it as 1.85:1 when the movie is actually 1.78:1 as is the original Blu-ray. 

Lionsgate Limited 4K Blu-ray see caps. Much better contrast and grain exposure but the grade is a bit questionable as it skews heavily towards magenta in some caps and the encode looks low-pass filtered.

Lionsgate and the upcoming Imprint have the same discs.

Lionsgate 4K Blu-ray encoded the "Original 5.1" as lossy Dolby Digital, which is very different from the AC3 on the original DVD.  This new "Original 5.1" may in fact be a downmix of the Atmos track.  FWIW, the original DVD AC3 still sounds very good.

Both Eureka and BFI Blu-rays are worthy of owning. Each restoration has unique positives and extras. The James Bernard score on the BFI is outstanding and the image tinting is different to how the Murnau institute official restoration was done. The Eureka MoC Blu-ray is stuffed with extras and remains one of the best-made Blu-rays of all time. Whatever you do: AVOID THE Kino Lorber Blu-ray!!! It uses the same Murnau institute restoration but drops frames for the whole feature - thus it loses a significant portion of the film! This was never acknowledged or addressed. The Kino Lorber Blu-ray remains one of the worst Blu-rays of all time for this reason.
