>>211460977The pilot (both versions) have official 4K versions remastered by David Lynch that came with the "From Z to A" box set that came out in 2019, and got a repackaged version this year. Part 8 of season 3/The Return also got a 4K remaster with this set. Finally, Fire Walk With Me got a 4K version (without HDR) within the last couple of years in Europe, and that version is being brought to North America this year. I think it also has the content from The Missing Pieces.
As for the series, The Entire Mystery (which was repackaged into From Z to A) is the 2014 Blu-ray release of the original series, Fire Walk With Me, and The Missing Pieces, and it was completely remastered from the original negatives and even color-corrected to have the red hue that the series is supposed to have. This version can be found through the usual places, but I ended up buying From Z to A after I wanted to get all the bonus features, of which there are a lot. Season 3/The Return is the other half of From Z to A, being a repackaging of its Blu-ray release (known as A Limited Event Series).
While the Definitive Gold Box Edition DVD set of the original series has basically been superseded and had nearly all of its special features carried over to The Entire Mystery, it was really good for the time and still has a handful of exclusive features that you can find online (ie. the SNL skit, Japan's Georgia Coffee commercials directed by Lynch).
>>211461256Lynch directed all 18 episodes of season 3, the original pilot, Episode 2, Episode 8 (the first episode of season 2), Episode 9, Episode 14, Episode 29 (the original finale), and FWWM. He is the co-writer of the series with Mark Frost, but he may as well be called the series director, especially since most of the episodes not directed by him before Episode 17 were done by people trying to fit it to his style.
