I'm trying to understand what you're saying. There isn't a single theatrically released "movie" in the last 100 years that's resolution is capped at 480p. Films took a resolution hit when they were scanned for broadcast on TV. The original film material has, in many cases, an effective resolution many times higher than 1080p.
For Example, the recent restoration of the 1939 film WIZARD OF OZ. The nitrate elements were digitally scanned at 8K for archival purposes. That's approximately 8 times the resolution of current 1080p.
As for TV. Interlacing was the method by which the material was broadcast, and not necessarily recorded. Many early TV shows video signal was direct recorded to film for archiving.
In fact, the WORST period in terms of longevity would seem to be the 80's and 90s, when finishing was done on video. So whereas the original STAR TREK can have it's original film negative scanned for release on BluRay, STAR TREK: TNG is stuck at 480i, since it was edited, and it's visual effects produced at that resolution.
But shows like ANDY GRIFFITH, GILLIGAN'S ISLAND, or LOST IN SPACE could all be released on BluRay, and benefit very much from it.
Here's a handy chart that shows the resolution of images from web all the way up to 8K. NTSC is #16, 720p is #14, and 1080p is #12:http://gadgets.boingboing.net/gimage..._bbg_large.png
