Director's: US Paramount Blu-ray > WB Blu-ray

Disney 4K Blu-ray, while a good release by itself, is very revisionist albeit made by Fincher. It has a huge amount of tinkering, a different grade, and at times uncanny with the sharpening. Caps of just how revisionist the new master is.

All Blu-ray tracks have significant limiting.

Disney 4K Blu-ray has some alterations, otherwise similar to the Fox Blu-ray

A blog article going over the home video history of Fight Club: https://notonbluray.com/blog/fight-club-compared-blu-ray-vs-itunes-vs-d-vhs-vs-dvd-vs-laserdisc/

The UK cinema version is the most complete version of the film to date, featuring additional scenes of violence. Additional footage includes:

• louder impact sounds during the fight scenes with added bass, particularly during the alley fight (the impact sounds are much tamer on all video and DVD releases)

• the use of nunchaku during the closing fight on the castle (the fight sequence now has no footage of nunchaku)

• an elbow-lock move performed during the above fight (this is now cut from all versions) It is assumed that this version is the cut of the film made before trims were made to it for the MPAA to secure a PG-13 rating.

The UK theatrical cut has not been released on home video to date.

• 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.
