Lady & The Tramp was actually animated in Full Screen and Widescreen versions.
Why is it that television commercials and music videos have been broadcast "widescreen" for over a decade yet no network is still willing to show films this way?
I know with the new "digital" broadcast some are, but that opens a whole 'nother can of worms as the NBC logo in the corner of the screen is cropped in half on my traditional tv set.
How do the previous 50+ years of television look on those new "widescreen" tvs? Black stripes up the sides of the picture? Zoom cropped to cut off foreheads and chins?
The "solution" is to use a video projector and thus "every screen" is the right size (and original aspect ratio can be maintained).
More often than not these days, "full screen" will give you more image at times (open matte) and less image at other times (special effects closeups, and some information that falls out of the "television safe" middle of the screen). Few people in Hollywood don't consider television broadcast in the lifespan of their films.
TV shows should be windowboxed on widesreen TVs (black bars on the sides).
We use a setting that "stretches" the picture horizontally slightly (essentially, anamorphic fullscreen, so to speak) -- it's a little strange for about 5 minutes, then you get used to it.
