Um, this is fantastic. Joss Whedon’s musical superhero tale is a bit of an Internet phenomenon, to put it mildly. I think tonight is the last time you can see this 43 minute film for free, but there are rumors buzzing that it might be extended a little longer than the original week planned. It’s also scheduled to be released on DVD at some point in the near future. Neil Patrick Harris is Dr. Horrible, Nathan Fillion is the hero Captain Hammer, and Felicia Day is the girl they both love. Great stuff.
