That's really cool. I'm wondering what the point of all the open matte films at the bottom of the list is? There were tons and tons of films (way more than this list) released open matte on DVD home-video, but they were clearly composed for widescreen.

Also, the filmed in (*) doesn't seem to make much sense. For some films (like On the Waterfront) it marks the aspect ratio the film was composed for, but on others (like BTTF and the films at the bottom) is marks the tallest aspect ratio available from the filming format regardless if the film was ever meant to be seen that way.

For the whole Kubrick thing (The Shining, Full Metal Jacket, Eyes Wide Shut) I believe the consensus is that he composed for widescreen, but he approved open Matte transfers for CRT home video because he didn't like black bars (he was a strange guy).

It's a very nice list. I had no idea that Star Trek 6 used the Univisium aspect for the DVD.
