Joss Whedon’s Dr. Horrible’s Sing Along Blog is a 40 minute musical that stars Neil Patrick Harris as Dr. Horrible, a bumbling, video blogging super villain who’s trying to get into the Evil League of Evil. The project is available on iTunes for $4 – this week Hulu also put it on its site for free with commercials.
The video is an experiment in a new type of video format that is professionally produced and designed to spread virally (although Whedon is stopping short of supporting BitTorrent trading). Whedon wrote a hilarious guest post on the Hulu blog about the show as well.

Update: So we’ve confirmed that the video has no international restrictions. Hulu has said in the past that they can flip a switch for any particular video to remove the U.S.-only restriction, but this is the first time I’ve confirmed it for a particular video.
