Dr. Horrible's Sing Along Blog is a 43-minute musical film produced exclusively for internet distribution. It tells the story of Dr. Horrible, the aspiring supervillian alter ego of Billy; Captain Hammer, his nemesis; and Penny, their mutual love interest. The movie was written by writer/director Joss Whedon, his brothers Zack Whedon (a television writer) and Jed Whedon (a composer), and Jed's fiancée, actress Maurissa Tancharoen. The writing team penned the musical during the WGA writer's strike. The idea was to create something small and inexpensive, yet professionally done, in a way that would circumvent the issues that were being protested during the strike. -wiki

This is a really good piece of creative work! So hurry up and watch it. I have the youtube parts here, in their chronological order. But you can also watched it streaming on the official site here.
David B., if you're reading this, the main character looks a lot like you (in his civilian attire).













Now, wasn't that amazing? And so somber an ending! I love Dr. Horrible.
