Update for you…
I have been in touch with The Criterion Collection and it’s head, Jon Mulvaney, concerning and suggesting SUPERMAN, and got a prompt response promising he will share that suggestion with his colleagues at Criterion. And yes, I did suggest they include all three versions of the film (they did with THE NEW WORLD, which is also a Warner title). Considering I did this now since the 40th anniversary is December 2018, if they do go through with this, it will take a long time getting it all together.
The URL is criterion.com if you fans want to suggest this too.
That’s good to hear, I’ll definitely message them.
In the meantime if anyone wants to preview part 2 on their 5.1 setup let me know. I am eager to get this out, but not before i can verify the sound is ok.
