I like most of what Joss Whedon comes up with (the Buffy the Vampire Slayer series and Firefly, for instance), so when I heard that he was involved in this site, I had to check it out. I’m not sure who plays Dr. Horrible, though he looks very familiar (he might be one of the guys who played a pseudo-evil teenage geek in Buffy on occasion), but I instantly recognized “Captain Hammer” as Nathan Fillion (“Captain Mal” from Firefly, as well as the big bad guy from the last season of Buffy).

The first two “acts” are online now, with the third marked as coming tomorrow… very amusing, check it out. But hurry, it’s supposed to stop on Sunday, after that it’s only available on iTunes.
