As you know, many years ago there was an attempt made by Alex Serpa to remix the extended 3:08 TV cut of SUPERMAN in 5.1 surround. While clips of this work still remain on YouTube, it never came to full fruition.

…we may finally have a completed attempt to do such a mix. Some of you know that the current Warner Archive Blu-Ray of the TV cut has flaws of its own in terms of the sound mix. But this new attempt will hopefully address this issue.
The guy that’s doing it goes by the call sign “Croweyes1121”. I will keep you posted on this development.
