@torb The cynic in me thinks they might be positioning this as a way of getting cheap HD or 4K editions from standard definition scans without the added cost of going back to the original film masters.
But the realist in me thinks that Adobe probably aren't that clever and it's likelier that they only used it because the copyrights for that particular movie weren't renewed so it's a decent quality public domain example they can use without worrying the legal department. 🙂️
