Update: the video originally linked in this article was evidently not from the source, so it was taken down. However, there is a link below to a legit video.
Joss Whedon is, simply put, a genius. While I never got into "Buffy" or "Angel", "Firefly" is far and away one of the best TV shows ever made, in science fiction or any other genre. In just a few short episodes he wove an entire universe together with characters I really cared about.
He has a new show coming out in January called "Dollhouse", about people who have volunteered to have their personalities rewritten over and over. It's disturbing and odd, but it looks cool. And they just released a trailer for it.
I found it on YouTube, but who knows if it'll be taken down or not. I couldn't find an original source for it, though io9 has it too. The SciFi blog io9 has a copy of it you can watch.
Warning: possibly marginally NSFW stuff, including a creepy and unsettling scene between an older guy (well, my ageish or thereabouts) and a young woman programmed to, um, well, fall in love with him.
I don't know what to make of all this, but it's Joss Whedon, so I know it'll be good.
