I'm definately interested as well.
I was watching the american and found it so funny how much our culture has changed (in some respects) in that, they changed the movie to appeal to the american public, and yet when I'm watching it, every time Raymond Burr was on the screen, I was wanting him to get his ass off my TV cause his bad acting and horrible scripting was ruining a good movie...
I want the original version released, restored.
Extras would be nice, but I don't even care, so long as it's the fully restored Japanese version.
