Back to the Future Part II (1989)

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.
