I see in my last post I didn't really explain the connections fully. When paying attention to the audio changes in conjunction with this credit change, they sync up with each other. The Mono Mix has the 'refined' credits, 16mm and bootleg. While the Dolby Stereo has the 'draft' credits. So since the audio differences were identified as opening day things, then this credit probably follows along.

So the weird thing now is, you would think since the 'refined' current credit version that it would have taken it's audio counterpart along to 'current' status, but it hasn't. The Mono Mix has been excised. Was the Mono Mix created last or all three being worked on simultaneously?

I can understand if they made the "refined" credits at the time when they were making new prints when the popularity grew or for foreign versions, but exclusively for the prints with the mono mix... why even have Dolby System on those prints? was Dolby compatible with Academy mono prints?
