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. Music by: Joss Whedon and Jed Whedon; Lyrics by: Joss Whedon, Jed Whedon, and Maurissa Tancharoen; Score and Orchestration by: Jed Whedon. Dr. Horrible's Sing-Along Blog is a 40-minute, 3-part musical comedy produced for the Internet, telling the story of a low-rent supervillain, the hero who keeps beating him up, and the cute girl from the laundromat he's too shy to talk to.
Dr. Horrible is filming an entry for his video blog, responding to emails from his viewers and boasts of his recent activities (a "75% successful" gold heist using a transmatter ray) and his plans for the future (creating a time-freezing ray). Dr. Horrible also introduces his nemesis: Captain Hammer. When a reader asks Dr. Horrible about the "her" that he often mentions, he launches into song ("Freeze Ray") about Penny, the girl he likes from the laundromat, whom he can't seem to get up the courage to talk to. Horrible hopes that his freeze ray will allow him the time to find the right words to say to her.
