This is a video near 40 minutes long created by a few writers during the writer's strike. It's purpose was to show the bigger corporations that writers don't need large budgets to create quality stuff. It's probably one of the best videos I've seen in a while. I think it accomplished it's purpose very well, while Dr. Horrible is played by Neil Patrick Harris.
