There’s an awesome miniseries out right now called Dr. Horrible’s Sing-Along Blog. The first act came out earlier this week, the second came out today, and the third comes out on Saturday — but they’ll only be up until Sunday unless you buy them on iTunes.
I suggest heading over to drhorrible.com and watching them now – they’re fairly short but awesome. They’re created/directed by Joss Whedon, the guy who made Buffy the Vampire Slayer and Firefly. They star Neil Patrick Harris and 2 people I’ve never heard of.
Thanks to John for the link!
