So, this thread is designed to list all Blu ray discs that come with 4K releases that were also upgraded for the release. This is supposed to be a helpful tool for movie collectors such as you or I.

Anyhoo, here are the ones I've found:

Star Trek: TOS movies (II-VI)
Unbreakable
The Back to the Future Trilogy
The Godfather Trilogy*

For me that's all the ones I've found so far. Feel free to add your discoveries!

*not always included with the 4K releases

A Christmas Story
Lost Boys
Poltergeist
Unforgiven
Lost Highway (Criterion)

Rudolph the Red Nose Reindeer
Frosty the Snowman
Spartacus
The Ten Commandments
Spartacus
Double Indemnity
A Christmas Story
Santa Claus is Coming to Town
Home Alone
It's a Wonderful Life
The Shinning

Top Gun
Batman
Batman Returns

The Matrix
The Matrix Reloaded
The Matrix Revolutions

A Christmas Story, yes, but Christmas Vacation is the same transfer as the second blu-ray release and not a remaster like the 4k (at least from what I read).

Adding:
Grease
Fright Night

Doh! you are correct about Christmas Vacation. Carry on.

That said, it's still a great upgrade from the first blu-ray release.

So...does anyone know if the new Original Star Wars Trilogy (episodes IV-V-VI) on 4K have corresponding Blu rays that have also been upgraded?

Also, how about the recent 4K release of Reservoir Dogs? Have they upgraded the Blu ray of that?

The Star Wars do. Maclunky.

Yes, the Blu-ray that comes with Reservoir Dogs on UHD has also been remastered. Both discs look considerably better than the prior Lionsgate Blu-ray.

Thanks.

I'm guessing that the Trilogy has also undergone even more "changes" (digital butchery) in the 4K era. Did they switch out Sir Alec Guiness with Jar Jar? *shudders*

Good to know!

Thank you all for the continued contributions to this thread!

Yes, hence stvn1974's reference to "Maclunkey."

Miami connection put out by Vinegar Syndrome. Their bluray included is from their 4k remaster. I'm still keeping my drafthouse bluray as well as its like watching it on a scratched up 35mm print.

Question:

Are the supplemental Blu rays to Pulp Fiction and The Road Warrior given 4K transfers?

Does anyone know if the Blu ray that comes with the Superman: The Movie UHD is a 4K transfer? WB gave one for A Christmas Story and The Matrix Trilogy, wouldn't they give one to Supes?
[Just found out: nope]

*crosses fingers for 4K Transfers of the Superman II (both cuts), III, IV, and the Star Trek: The Next Generation HD Blu rays with their UHD releases*

I know The Return of Swamp Thing 4K set reused the older special edition BD.

2001: A Space Odyssey
Heavy Metal
Field of Dreams
Flash Gordon
Ghost in the Shell (1995)

The standalone Superman The Movie UHD that is out now does come with a remastered BD using the same transfer. Both the UHD and BD are the theatrical cut. Some people don't like the transfer and the rumor is that the upcoming Superman UHD box set is going to include another go at the Superman The Movie transfer but it will only be available in the set and not on its own.

Yep, Superman has received an improved Dolby Vision grading coming in the new set.

Quick question: does The Road Warrior (1981) have an upgraded Blu ray with its accompanying 4K release?

Also: has anyone seen any other Blu ray upgrades with their 4K counterparts?

Seriously: does anyone know if they spruced up The Road Warrior Blu ray? I'm sure the 4K disc looks good, but I would really like to know if the 2K disc got some love too.

Big thanks to anyone who can answer this question before I consider getting it.

I'm pretty sure the Road Warrior blu-ray is still the old one. No new remaster.

Thank you for letting me know! It means a lot.
