Blu-ray

Universal 4K Blu-ray - caps. Looks stunning against the horribly neutralized old master. Very glad Deakins supervised the new grade and had Universal restore his color filters.

Universal Blu-ray (included in the 4K edition) has the original 5.1 mix not on the 4K disc 

The original 5.1 surround mix from the 2011 USA BD was included alongside the new Atmos upmix. The compatibility track is a downmix of the Atmos. The Atmos is overall lightly remixed with noticeably more high frequencies rolled-off relative to the old 5.1. I think the 5.1 sounds better. The 5.1 mix from the USA BD was used as it sounds essentially the same as the EUR BD (with some minor loudness differences) while not featuring the dither noise and low frequency noise that the EUR has. Commentaries between the USA UHD and USA BD are the same, with both featuring Dolby Surround metadata

Audio comparison: 5.1 surround

Caveat: mostly great video but the 4K Blu-rays have had additional DNR applied in some scenes on top of the DNR that had been applied in post-production and was already present on the DVDs & Blu-rays

The 2020 Blu-ray (the one without the green tint) may be better than the 4K Blu-ray?

New Line Blu-ray have the original 6.1 mixes

4K Blu-ray set is missing extras from the old Blu-ray/DVD releases

The 2011 Blu-ray notoriously had a green tint, the 2020 one removes it.

(see video/audio notes)

The original master is of poor quality, blurry with some damage and bad levels, which the 4K remaster improves upon, with better detail in compression. Unfortunately, the 4K master has significant issues with color posterization, making it look like poor quality digital video rather than 16mm film.

Well Go does not include the dub.

> Canada Alliance Blu-ray see caps

France/Italy has Blu-ray, no US/UK releases

CA Alliance Blu-ray or dutch Blu-ray are the same masters but have additional sharpening.

The original DVD has an isolated score and a exclusive easter egg

Kino Lorber has Blu-ray, not sure if IS/EN are newer restoration https://nwfilmnewsroom.wordpress.com/2014/03/20/russian-ark-brand-new-4k-restoration/

UK Indicator is good, not sure about US

> US WB Blu-ray

WB Blu-ray has 24 bit DTS-HD MA

Germany Century³ Cinedition - Director's Cut Blu-ray has exclusive extras

The Universal Blu-ray is slightly filtered and DNR'd compared to the HD-DVD, and the Universal 4K Blu-ray, on top of being upscaled, adds additional DNR and is softer than both previous HD releases.

Versions:
- The International version contains a short additional scene (part of the "Farmhouse" extended scene from the special features). See additional detail below.
- The US version does not contain this scene during the film. Director Doug Liman confirms in his audio commentary that the scene was cut from the original US theatrical release "for time".
- "The Explosive Extended Edition" found on some DVD releases is not an alternate cut of the film, simply an access mode that plays "The Bookend Scenes" features via non-seamless branching.

Deck the Halls scene:
The U.S. release is 118:17 while the European/Australian/Japanese releases are 118:36. There is no difference between the two running times from the start, but at 81:21, the U.S. version cuts from a kitchen scene of Marie and Eamon washing dishes, to a scene of Eamon bringing blankets to Jason and Marie. On the European/Australian releases, at the same point, there is a scene of Jason, Marie, Eamon and his children eating dinner while "Deck the Halls" plays in the background. There is no dialogue, the characters just each exchange uncomfortable glances. The scene goes to 81:40, then picks up the same scene of Eamon bringing blankets. This scene is included as an extra ("Farmhouse" extended scene) albeit sans the holiday themed music. Many thanks to Rewind user Mark Bowen for comparing these releases and letting us know the difference.
