Well not THE Dr. Horrible, but Neil Patrick Harris will provide the voice for the Music Meister in an upcoming Batman: The Brave and the Bold episode.
The Music Meisterâ€”an amalgamation of various DC Comics villainsâ€”â€œhas the power to create song wherever he goes, and heâ€™s trying to dominate the world,â€ Tucker says, before pointing out that the episodeâ€™s â€œplot itself is just the framework, an excuse to have everybody sing!â€ Tucker and producer/story editor Michael Jelenic wrote five original songs for the episode.
Yes, Batman: The Musical!
If you are attending the San Diego Comic Con, you’ll want to check out the Warner Bros. Animation panel on July 24, 2009 at 10:00 AM, where the episode will debut.
