Dr. Horrible will star in a Batman musical

It seems there’s nothing Neil Patrick Harris can’t do: He was the title character in Joss Whedon’s Emmy-winning, all-singing, all-emoting Dr. Horrible’s Sing-Along Blog; he wowed us at the Emmys; and now he’ll be voicing and singing a new character in an upcoming musical episode of Batman: The Brave and Bold, the animated TV series, next week.
