EXCLUSIVE: Nathan Fillion Hints At More Than Just A Sequel For 'Dr. Horrible's Sing-Along Blog'

Around Splash Page HQ, "Dr. Horrible's Sing-Along Blog" is considered one of the on-screen highlights of 2008 — right up there with "The Dark Knight" and "Iron Man." So it's pretty much a given that any time we get a chance to speak with someone involved with the hit online musical, we're going to ask about the "Dr. Horrible" sequel.

Cue our encounter with "Castle" star Nathan Fillion during last night's Cosmopolitan Magazine "2010 Fun Fearless Males" red carpet, and his hint that there could be more in store for the "Dr. Horrible" universe than just a sequel.

"I've heard some of the lyrics for one of the new songs," Fillion told MTV News. "I've heard a title for the sequel, and I've heard some great ideas. I've also heard of some kind of other accoutrements that are coming out aside from a sequel that we're planning on."

"So... exciting things. 'Dr. Horrible' [is] far from dead," he added.

As for what those accoutrements might be, Fillion wasn't talking.

"I can't. No," he answered when asked if he could shed any more light on the mysterious peripheral projects.

And he had good reason to keep quiet. According to Fillion, breaking silence on "Dr. Horrible" would ensure an untimely end via "a lightning bolt from god."

So, in the interest of protecting our Captain Hammer, we'll just have to wait to find out more... for now.
