I recently received the hot off the press Dr. Horrible's Sing-Along Blog DVD, and watched it through three separate times the past couple of days. First, just to savor the whole thing on a regular TV screen (I had previously watched it streaming on my PC, in iTunes and then again on my iPod). Then, I watched the DVD with the cast and crew (talking) commentary. Finally, I watched it with "Commentary: The Musical!" turned on. In case you didn't know, this is an episode "commentary" where the cast and crew sing all new songs, addressing such subjects as why Nathan is better than Neil in ever way, the writers' strike, why nobody wants to be "Moist" and Felicia's acting "process."
For fans, this thing is a total treat. Even if you've already seen Dr. Horrible (which made an incredible number of year end "10 best" lists), you really need to pick up the DVD. In addition to the program itself and the commentaries, you'll find a making-of program and several very funny fan applications for the Evil League of Evil.
Dr. Horrible Site can be found here, with links to iTunes (for the original) and Amazon (for the DVD).
They still haven't published the lyrics for "Commentary! The Musical" on the official site yet, but I did find where someone online had done a great job of transcribing them. I put them in a google docs document here.
Make a resolution to start your new year Horribly!
