Im a little confused about ET, are the full screen dvd’s open matte for some shots but not others ?
When I last saw the 20th anniversary 4:3 DVD, I remember the OP/ED credits and actors only scenes like the one with Elliot’s brothers at the table had alot more vertical information (but loses a bit on the sides) compared to the widescreen theatrical cut on disc 2. That scene there (and a few others) is clearly matted top and bottom while gaining some side information. On the shots with ET and the VFX, they are clearly side cropped but do gain a bit on the top and bottom, meaning they were hard matted/animated somewhere at around 1.66 so cropping to 4:3 wouldn’t be such a mess.
