VIDEO: Preview - DR. HORRIBLE'S SING-ALONG BLOG Makes TV Debut on The CW, 10/9

Joss Whedon's original DR. HORRIBLE'S SING-ALONG BLOG, which also stars Nathan Fillion and Felicia Day, will make its television debut on Tuesday, October 9 (9:00-10:00 p.m. ET) on The CW. Watch a preview for the television premiere below!

Created as a three-part online musical, the series stars Harris as Billy, A.K.A. Dr. Horrible, a budding super villain whose plans for world domination continually go awry. His two goals: getting accepted into the Evil League of Evil, and working up the guts to speak to his laundromat crush Penny (Felicia Day, "The Guild"). The only thing standing in Billy's way is his superhero arch nemesis, Captain Hammer (Nathan Fillion, "Firefly," "Castle"). With one big score, Billy could get into the E.L.E. and earn the respect of Penny, but only if he can keep her away from the dashing Captain Hammer.

The special was written by Maurissa Tancharden, Jed Whedon, Joss Whedon and Zack Whedon, with music by Jed Whedon and Joss Whedon.
