The show is described as:

“It’s the story of a low-rent super-villain, the hero who keeps beating him up, and the cute girl from the laundromat he’s too shy to talk to.” says Whedon.

“Doctor Horrible’s Sing-Along Blog” will star Neil Patrick Harris as Dr. Horrible, Nathan Fillion as Captain Hammer, Felicia Day as Penny and a cast of dozens.”

Neil Patrick Harris as a low rent supervillain is a stroke of genius. If you’ve ever seen him as Barney on How I Met Your Mother or in the Harold and Kumar movies, you would agree. Over the years, Harris has been consistent, and recently consistently funny. This is the most exciting bit of casting.

Then there is Nathan Fillion as the “hero”. Another great bit of casting. With all the work that Joss has done with Nathan over the years, you wonder if he wrote Captain Hammer with him in mind. Fillion is an underrated actor who just can’t seem to cut a break. Both “Firefly” and “Drive” were cancelled before their time, and “Slither” was sinfully overlooked. Hopefully his recent success on “Desperate Housewives” is just the start.

Felcia Day is less known but has been a guest on many shows in the past. She looked familiar, and then I realized I remembered her from her short time on Buffy as Vi. I went back and watched a couple of the episodes and realized why I still recognized her. Her perfect portrayal of Vi is what made her the most memorable of the “potential slayers”.

I am very much looking forward to this “little internet project” of Joss’. Hopefully, it’ll turn out to be bigger.
