A "Dr. Horrible's Sing-Along Blog" sequel might actually happen. According to Variety, Joss Whedon plans to do a follow-up to the 2008 Internet sensation "within the next year."
Starring Neil Patrick Harris, Nathan Fillion and Felicia Day, the original "Dr. Horrible" came about during the most recent Writer's Guild of America strike. Whedon penned the project with his brothers Zack and Jed Whedon and Jed's wife Maurissa Tancharoen. Presented online as a miniseries, the musical took off -- as things Whedon touch are bound to do -- and became a cult hit.
Whedon has his hands full as of late. After the success of "The Avengers," the "Buffy the Vampire Slayer" creator was tasked with writing and directing its follow-up due out in May 2015 and signed a deal with Disney to help oversee Marvel Comics-based TV projects. It was recently announced that Whedon, along with his "Dr. Horrible" writing partners, would pen a TV pilot following the Marvel universe government agency S.H.I.E.L.D. If the timing works out, he'll also direct.
The ABC pilot is going into production immediately, but no casting has been announced. HuffPost TV couldn't resist coming up with a little dream cast list.
