I'd love to see Jaws 3-D in... well, 3D!
I saw in in 2D at the local cinema when it was released, but it always felt like there was something missing.
You can get bootleg anaglyph 3D DVD versions off eBay, but I suppose the ideal preservation would be in a side-by-side format for playback on a 3D TV with Stereoscopic Player? I don't actually have a 3D TV and this sort of thing is a bit new to me.
