Mining for pop culture gold on the internet

One of the most amazing things about the internet is its ability to bring to light forgotten movies, TV shows and other cultural works.
For example, I encountered a link to this BBC adaptation of Aldous Huxley's brilliant book Brave New World. I haven't yet dedicated the three hours necessary to actually watch it, but it pleases me to know it is there when I want to.
On the radio side of things, the BBC also did a dramatic adaptation of Isaac Asimov's Foundation Trilogy.
I'm sure with a bit more digging, I'd be able to find all sorts of other BBC productions of classic science fiction works.
Another radio adaptation  I unearthed recently was Samuel Delany's The Star-Pit. There are even some notes by Delany himself on how the adaptation came to be.
Got any hidden radio or TV gems out there that you want to share?
