Neil Patrick Harris Joins 'Batman: The Brave and the Bold' As Musical Villain

Neil Patrick HarrisJust when the "Batman" news couldn't possibly get more depressing, here comes Neil Patrick Harris to save the day. The former Dr. Horrible is going head-to-head with the Dark Knight -- in animated form, at least.

The "How I Met Your Mother" actor will provide the voice for the Music Meister, a brand-new villain created specifically for "Batman: The Brave and the Bold." Harris' character will appear in an episode called "Mayhem of the Music Meister!," set to debut during Comic-Con International.

In the episode, the Music Meister -- a bad guy that's allegedly "a combination of various DC Comics villains," according to Buddy TV -- sets about the globe, using his powers of spontaneous song construction to dominate the world.

Sounds a little thin? That's because it is, as "Brave and the Bold" producer James Tucker freely admitted to Buddy TV: "[The] plot itself is just a framework, an excuse to have everybody sing!"

Neil Patrick Harris is well-versed both in song and geekdom, having previously combined the two in Joss Whedon's internet series "Dr. Horrible's Sing-a-Long Blog." The series -- which Whedon said would make for a great comic book -- certainly prepared Harris for the Music Meister, a role which Tucker said the actor pulled off with ease.

"[It's] something [Harris can] contend with, as opposed to just a lark," he said. "It feels polished because of his vocals. And not just his singing, but his acting as the character, too. He nailed it. I showed him some drawings [of the character] and he got it instantly."

"Mayhem of the Music Meister!" will premiere at Comic-Con International's "Batman: The Brave and the Bold" panel on Friday, July 24 at 10:00 AM PST.
