Regarding Top Gun, the original R1 DVD release has both widescreen and fullscreen versions on the disc. The widescreen version is 2.00:1 though
an idea I had with Top Gun was to have three different versions on a BD-25 (in SD) and the option to toggle between aspect ratios (1.33:1, 2.00:1 and 2.35:1) but have them all synched up to the same soundtracks
