You’re buying a projector screen to perfectly fit one movie…? That seems kind of absurd to me, sorry.

Also, not every release of the same movie will have the exact same dimensions due to the nature of how it was scanned and restored. So, for example, the new 4K box set coming out in a few months might be slightly wider than the 2011 Blu-Ray, which might be slightly wider than Despecialized, which might be slightly wider than 4K77… etc. etc.

Not to mention when you pop in another “scope” movie, it won’t be exactly the same dimensions either.

And what about 1.78:1 content? 1.85:1? 2.00:1? 2.76:1? Good old fashioned 1.33:1?
