Sony

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.

Sony 4K Blu-ray Steelbook upcoming with Dolby Vision and both cuts in 4K

The LPCM 5.1 from the old Extended BD and the DTS-HD 5.1 from the new Extended UHD are exactly the same. The DTS-HD tracks on both of the theatrical UHDs are also the same, and in fact appear to be lossless versions of the Superbit DTS mix with no tampering.

Side note, CA Alliance Blu-ray is open-matte, not original aspect ratio, and visual effects are cropped too.

HDR caps by fkid. Obviously this is a huge improvement after what was available until now. Still, the early 2000s nature of the film is palpable and more noticeable, f.ex. in the opening scene that looks upscaled but seemingly without AI usage or any egregious tools. No info yet about what Fincher actually changed and where he tinkered around. Also see samlop10's review
