Joss Whedon's supervillain tragi-comedy gets the 8-bit treatment in this fan made video. Neil Patrick Harris stars as an aspiring supervillain competing for a mutual love interest against his arch-nemsis, Captain Hammer.

Dr. Horrible's Sing-Along Blog—the Joss Whedon-penned musical starring Neil Patrick Harris as a video blogging, musical-loving supervillain—is going to get a full-on live performance at tomorrow night's Emmys, EW's learned. You can watch the entire thing here:

Whedon fans are a nerdy sort, and certainly if the source video links can't be unearthed and the files downloaded, it can always be captured with software, and then distributed on file-sharing networks. Of course, truefans will make noises about then the artist won't be getting paid, but then there weren't exactly enough truefans to save Firefly, and that didn't even have dance numbers.

In a world where musical theater devotees and sci-fi fans yearn for common ground, the trailer for Dr. Horrible's Sing-Along Blog grabs you by the lapels and sings, "I am that rare beast of boogie-woogie/for fans of Buffy/and fans of Doogie." Penned during the writers strike (ssshh!), the three-part internet series (helmed by Buffy creator Joss Whedon) stars Neil Patrick Harris as timid villain Dr. Horrible, who's about as skilled at wooing cute girls as he is at defeating good guys — which is to say, not very. Two pressing questions: how will Whedon fare in a medium free of low ratings and premature Fox cancellations? And also, is Neil Patrick Harris doomed to play a blogger for the rest of his career?
