You’ve heard of Dr. Horrible’s Sing Along Blog, right? It’s an Internet only project from Joss Whedon about a supervillain who wants to rule the world, but is constantly thwarted by his arch nemesis Captain Hammer and secret crush Penny. There are three acts to this comedy/drama/musical, all of which have now been released and are available for FREE at DrHorrible.com for a very limited time.

All episodes will be pulled at midnight this Sunday, so hurry over and watch. It’s darn good stuff, especially if you have an internet crush on Neil Patrick Harris, which I do. But it’s still good even if you don’t for some weird reason. Great comedy, touching drama, impressive music, the whole nine. Plus it’s got NPH. Did I mention that already?

Dr. Horrible’s Sing Along Blog also stars Nathan Fillion (of Firefly, Serenity, and Desperate Housewives fame) as Captain Hammer and Felicia Day (of Internet Sensation The Guild) as Penny.

Now go! Hurry up! And if you don’t get there in time, it’s also available for purchase at iTunes and later (according to rumors) on DVD. But for now, it’s FREE!
