There are many Disney films I'd love to see restored and given the Bluray treatment...it seems they aren't interested in thier legacy films, only the Marvel or Star Wars properties!!
Finding the 2003 remake on BRD, and not the 1974 original being released in the same format has me scratching my head. From what I'm seeing, it's in the Disney collection...that should tell you why it is not available on BRD. I've found them to be pretty lazy about doing justice to thier earlier...
