1.85:1: Kino Lorber 4K  / Capelight 4K

1.66:1: Criterion 4K but low pass filtered

Comparison between the 4Ks, Criterion on the AR choice

Other discs have unnecessary filtering and sound worse, the difference isn't substantial but audible

Arrow has 4k transfer

2025 Universal 4K Trilogy Steelbook / 2026 standalone is better than previous disappointing 2022 4K Blu-ray (excessive DNR). Not a whole new scan but the grain has been left mostly intact.

Cinema DTS is OG 5.1 mix.

Otherwise: 2022 4K Blu-ray’s DTS:X remix is more faithful than 2026’s Atmos remix.

3D Blu-ray’s 7.1 remix has reportedly less distortion than the OG 5.1 mix, and is presumably more faithful than the DTS:X remix.

This disc defaults to a lossless 5.1 remix, however in the setup menu, the original mono mix is included as a lossy alternative for the first time since the dawn of home video. The film was given a stereo remix very early on and remained stuck that way for decades.

Disney 4K Atmos is great, a reference quality track. It's a very slight remix (music seems to be from a better source), but it's completely seamless and faithful to the original, better fidelity than anything since the 1994 30th Anniversary Edition LaserDisc.

All DVDs (and 2010 Blu-ray) sound far worse than the 4K Blu-ray/LaserDisc and have various missing sound cues.

• 4K caveat: A variety of VFX set pieces and touch-ups were added in scenes throughout the film, probably for continuity or consistency, although they might be unnecessary or revisionist. Clouds are added to clear sky of the last act.

• AI is used to fix an unwanted camera movement in one scene.

• some shots had been further stabilized, resulting in strange motion blur.

Also has missing dialog intact.
But it can be argued that the Warner Bros 4K Blu-ray 5.1 (remix) is technically a better mix.
