This may be a stupid idea... but...
Okay, this is sort of a fantasy, because I haven't the resources or the time to do this, BUT:
My idea was to take an old episode of Star Trek, extract all the sound, and use that to create a brand new production entirely in 3D. The one I'd pick would have been The Doomsday Machine, Galileo 7 or The Enterprise Incident... or maybe Balance of Terror (Mark Leonard's first appearance in Trek... he went on to become the iconic Sarek, but I digress)...
Now, this could conceivably be done by just about anyone with the resources to do it with just about any screen production out there.
The most logical choice would be "It's a Wonderful Life" which has no copyright as it expired. (That's why it's played over and over and over again...)
Extracting all the sound out of it would be a simple thing. Animating it, not so simple and rendering it... that would require a render farm, which I can't afford, so for me to do something like is... well, kinda dumb for me to even try.
But for someone with the gumption and resources to do so: my thinking is if some group of anyone out there who wanted to start up a production studio, that would be the way to prove themselves.
I truly believe all the tools are now in place for this to be done in either DS or Poser or both... It would just take someone with the energy and drive to do it...
On that note: here's a list of movies who's copyright has expired:
