Caveat: does not contain natively shot expanded IMAX aspect ratios

> Knockout collection original.

The Mono mix on the initial release of the Knockout Collection is a stereo fold-down of the 5.1, it also has a missing piano cue. The replacement disc and the ultimate knockout version fixed the error. 

The Steelbook and UK standard edition is the same disc as the 2023 knockout collection.

Caveat: the 1.33:1 ratio is NOT included. HDR is sometimes bright.

4K Blu-ray has various issues holding it back despite the new scan. No Academy ratio version is included. The new remix audio is louder, harsher and nowhere near as good as the original. The original option on the 4K Blu-ray is processed and sounds lackluster. The LaserDisc sounds best by far with the Warner Archive Blu-ray coming in a close second.

Caveat: both releases do not contain their natively shot expanded IMAX aspect ratios

Warner Bros 4K Blu-ray caps. Original 1.85 framing restored, much better colors, image detail and a film stock-like tone curve was restored.

Warner Bros HD-DVD has the original 6.1 mix in a better format than the Blu-ray (Dolby Digital Plus instead of standard Dolby Digital), but is still lossy and a disc prone to disc rot. The Blu-ray is a good alternative.
