Conceived as an online miniseries event during the 2008 writers' strike, DR. HORRIBLE'S SING-ALONG BLOG is a 42-minute musical romp that bears the distinctive stamp of Joss Whedon. Neil Patrick Harris (HOW I MET YOUR MOTHER) plays the title character, who video-blogs about his twin goals to join the Evil League of Evil and to woo the fair Penny (Felicia Day, of Whedon's BUFFY THE VAMPIRE SLAYER and the Web series THE GUILD), a woman he met at the local Laundromat. Dr. Horrible is foiled on both fronts, however, by his arch-nemesis, the self-absorbed superhero Captain Hammer (Nathan Fillion, Whedon's FIREFLY). Directed by Josh Whedon. Starring Neil Patrick Harris, Felicia Day, Nathan Fillion, and Simon Helberg.
