Star Wars Episode 1-6 3D (Partially Lost 3D rerelease, 2013)

Wasn’t Blu-Ray 3D discontinued or something?

Yes and no. It's definitely not all that popular anymore and it's hard to find a 3D tv or Bluray 3D, but it still seems to be around. You can still buy Bluray 3D copies of new films such as the Aladdin remake and even Rise of Skywalker on Amazon for about the same price as a 4K. 

I did some more research last night and found some interesting information about these rereleases. According to a rumor from Making Star Wars, a reliable Star Wars fan site, a Bluray 3D collection of the prequel trilogy was considered in 2016 to hype up Rogue One heading to theaters.

This lines up with what we know so far about these releases. Attack of the Clones and Revenge of the Sith were shown at Star Wars Celebration in 2015 so it would've been on Disney's mind to release the trilogy around 2015-2016. Force Awakens was released on Bluray 3D around this time as well, being released in November 2016 even though the regular bluray release was in April 2016. This could mean that originally the prequel trilogy 3D was planned to be released the same day as the Force Awakens 3D to hype up Rogue One. Either way, we have a timeframe of when the release was considered. On a side note, the article didn't mention the original trilogy having any 3D release, which adds to my theory that the original trilogy 3D was only planned but never actually worked on.

Outside of this I found two different Amazon links for Phantom Menace bluray 3D. One is from Amazon US and the other Amazon UK. The Amazon UK listing actually has a placeholder box art which was a cool find. Neither have a release date or a way to buy them, meaning they were likely placeholders in case Lucasfilm actually decided to release them.

Thats all my findings for now, but I'm going to look some more later to see if there's anything else to add.

I never heard about that, so far all I've dug up is the Star Wars Celebration showings. I'll look into that!

I doubt the original trilogy ever ended up being remastered into 3D.

That’s not really what I meant. What I was saying is that Episode I 3D did relatively poorly at the box office, and then Disney’s buyout of Lucasfilm was finalized shortly afterward, and Disney had absolutely no interest in the prequels at the time, and also felt that continuing the 3D theatrical re-releases would distract from the movies they had planned. The second two were only shown at the Celebrations because they were already completed by those respective dates, I would guess (not to mention that critics, prequel haters and average moviegoers are basically a non-issue at something like Star Wars Celebration - almost everyone there would be excited to see them).

After finishing the 3D prequels, Lucasfilm’s work force would probably be too busy working on The Force Awakens and Rogue One to remaster the OT into 3D anyway (which is a shame, because in retrospect, I would have rather gone to see the first six movies in theaters in 3D than see any of the post-buyout movies in theaters in ANY-D).

On a semi-related note, was The Clone Wars movie ever screened in 3D when it was still in theaters?

Finally a Lost Media subject I can actually have some connection to...

The First Time I saw a Star Wars Movie (other than Lego Star Wars The Padawan Menace) was the Episode 1 3D Rerelease... If I recall the theater I went too had special 3d Glasses with either Darth Maul or Queen Amidala theming...

I think there was an article in the Star Wars Insider Issue 131 where they mentioned plans for doing a 3D rerelease of AotC and RotS... Although it might have just been something like "it'll be cool to see this..."

I think I have that issue somewhere...

Not sure if it helps but I thought you'd like to know...
