One of Joss Whedon's new projects, "Dr. Horrible's Sing-Along Blog," stars Neil Patrick Harris, Nathan Fillion, and Felicia Day. It's a musical web short, coming soon, though I'm not sure exactly when. For more information, check out Whedonesque. You know me, I tend to like everything Joss, but Neil Patrick Harris as Dr. Horrible? A SINGING Dr. Horrible? Who doesn't want to see that?!
