I’m a huge Joss Whedon fan and I was very much entertained when he did Dr. Horrible’s Sing-Along Blog and got Neil Patrick Harris and Nathan Fillion to star in them. The internet movie was only less than an hour long but it spanned such a huge following among Whedonite cultist that a feature film rumor doesn’t seem like a bad idea. I’d watch one, if it did happen. But is it going to happen?

There’s word of it being in development and when MTV talked to Neil Patrick Harris recently, the actor has apparently said, “Apparently they’re making a Dr. Horrible sequel, a feature film I hope… I hope they cast me in it… We’ll see. I don’t know what scale, they’re talking all options, because they made the first Dr. Horrible in five days on no budget at all… You don’t want to make the feature film be an $80 million giant movie, because it defeats the purpose of what the first film was made to be, but then again you don’t want it to be so low brow that it’s not worth paying money to see as a movie.”

The actors are now all working out a schedule so that they can begin with filming the scenes. No word yet on what studio is going to back this project up.
