Figured this warranted it's own thread.
Lord of the Rings, both theatrical and extended cuts are now out on 4K Blu Ray. Both editions have also had their digital versions upgraded to 4K/Dolby Vision/Dolby Atmos on the major digital platforms (iTunes, Google Store etc.) - so if you previously owned them digitally, you don't have to buy them again.
The Hobbit has also seen the same treatment.
The 4K releases are being very well received across the board from reviewers.
*At this time there is a "glitch" with the 4K digital release of Return of the King (Extended Edition) where it hasn't been upgraded/made available yet. All other movies have been upgraded.
