The trailer for Dr. Horrible’s Sing-Along Blog, an upcoming “Internet musical” featuring Neil Patrick Harris, Felicia Day, and Nathan Fillion, was leaked online yesterday, giving us a first glimpse into Joss Whedon’s latest creation. According to Whedon, “It’s the story of a low-rent super-villain, the hero who keeps beating him up, and the cute girl from the laundromat he’s too shy to talk to.” Harris, who has seen a surge in popularity with his cameos in the Harold and Kumar movies, plays the super-villain protagonist, with Fillion as the antagonistic “hero” and Day as the love interest.

Whedon, of Buffy the Vampire Slayer fame, said in a recent LA Times article that the project emerged from last year’s writer’s strike as a way “to get out there and create jobs and tell stories, and really [explain] to people that there really is another way.” Co-written by Whedon, his brothers Jed and Zack, and Maurissa Tancharoen, the show took only six days to film. By the time production on Dr. Horrible was set to begin, however, another one of Whedon’s creations, Dollhouse was picked up by Fox, and fast tracked into production. At the time Whedon said he felt that he “wasn’t going to abandon or short-shrift either project. You just can’t.”

Looking at the Dr. Horrible website tells a different story. Featuring only the trailer, hosted on Vimeo, and a series of broken links, we get no information about the show, nor a schedule for release. In fact, the only place to get any details is through the show’s fan site, DoctorHorrible.net. Apparently we can expect three ten minute episodes, most likely to be released sometime between now and Comic Con in July, where Whedon and the cast will appear on a panel. According to Harris, Whedon is still working on channels of distribution for the show itself.

Hopefully the show will be a hit; so far, it’s been an inauspicious start to the star-studded production.
