- Interviewer: Speaking of which- has there been any movement on a Dr. Horrible sequel?

Q. There’s been talk of a sequel. How far along is the planning for it, if at all?
JW: We have some songs, a rough outline, and no time. Though I have a feeling that when Joss is finished making his massive, expensive superhero movie, he will want nothing more than to make a tiny, cheap superhero movie. With songs.
Q: We’ve seen some of the other villains in the “Dr. Horrible” universe — well, a quick scene — would it be possible to see other heroes in a sequel?
JW: At the risk of spoiling — yes. There will be other heroes in the sequel. Perhaps even a council of them. A Council of Champions, if you will.
on July 2011, Joss Whedon was on Comic Con.
Q: Can we expect to see a Doctor Horrible 2 anytime soon?
JW: The thing that you have to understand... is yes.
There has also been word that they are trying to get Dr. Horrible 2 to debut on the 5th Anniversary of the first movie (June of 2013)
Obviously, that did not happen.
