What you haven't hear of Joss Wedon's latest project? For shame!
It's called Dr. Horrible's Sing-Along-Blog. It stars Neil Patrick Harris (who's awesome!), Nathan Fillion & Felicia Day. It's a super funny musical take on the super hero genera. Catch it free while you can online. If you miss it, you might try getting it on iTunes for a few dollars if you can't wait for the odvious DVD release.
I so hope we are going to see some more of these mini episodes from Joss Wedon in the future! I really commend Wedon on trying out a new format and distribution model for Dr. Horrible. Hopefully this will show the big studios and networks that you can make money by giving away your media.
