Though it's hard to know whether there will be much singing (a mechanism that doesn't work very well in comics) in it, Dark Horse will unleash a brand new comic spun from Joss Whedon's "Dr. Horrible" universe this fall.

While fans initially suspected the comic would collect previously-published comic strips from the Web, Dark Horse promised all new material at Comic-Con, which seems supported by the concepts that have sprung up at artist Joelle Jones ("You Have Killed Me") at Superpouvoir and Blog@.

In addition to Neil Patrick Harris' grim Dr. Horrible visage, Jones has sketched Penny, Moist and Captain Hammer with playfully accurate actor likenesses.

The issue will be written by Whedon's brother Zack, who, along with Jed Whedon, contributed to "Dr. Horrible's Sing-Along Blog" in the music department. Perhaps there will be a musical element within the title after all?
