Wow, never heard of this until now… then again, after the Superman movies and their alternate cuts for TV this isn’t surprising. I sent you a PM (if you can share a link), I hope you could find this material in good shape, I’ve seen a few clips and they don’t look good.
I did. I used upscaled footage from old VHS tapes and a few DVR recordings of the TV version that aired recently (within the past 2 years).
I’ll send it to you
