Q. Nathan Fillion and Neil Patrick Harris in an Internet musical in which the lovable loser baddy is kind of the good guy, and the good guy is kind of a dick—and it’s a musical?! Um, how? Wha? How on earth did this develop?

A. Who is to say who is the villain and who is the hero? Probably the dictionary. But I know that people who grow up identifying with outsiders are the people I are. Plus singing is the universal language, along with being on fire.

Q. You worked with Nathan on the last season of Buffy—he was scary and he thumbed poor Xander’s eye out!! I hate him! But, oh, he was awesome in Firefly and Serenity, so I love him!—but how did you hook up with Neil Patrick Harris for “Dr. Horrible“? Do geek heros (or heros of geeks) just hang out in all the same places?

A. You can go to Famousperson.org and rent them. You can also get lesser celebrities on EBaio. Hey-oh!

Q. Nathan Fillion strikes me as a great big pirate/cowboy sort of man-among-men. Surely such men cannot sing! Can he? LIke really?

A . Nate’s got pipes. (But we used Marni Nixon’s voice anyway.) There’s very little Nate can’t do. He’s a renaissance man! Like with the sculpting and the Italian guys!
