A trailer for Joss Whedon’s 36-minute three-part SCi-Fi internet musical Dr. Horrible’s Sing-Along Blog has hit the interwebs. Neil Patrick Harris stars as the title character, a low-rent supervillain who’s trying to impress the cute girl from the laundromat he’s too shy to talk to (Felicia Day of Buffy the Vampire Slayer), defeat his nemesis, superhero Captain Hammer (played by Firefly’s Nathan Fillion) and gain entry into the Evil League of Evil. Whedon penned the musical with his brothers (Zack and Jed Whedon) during the writers’ strike earlier this year. Check it out below and tell me what you think in the comments!
