OMG, How... HOW!!! did I miss this interview with Joss Whedon by 'This American Life' on NPR. I feel like such a fool!
Don't let this happen to you... click here and listen if you haven't already (the interview is from Sept 23rd and he discusses Buffy and Firefly and Dollhouse and Dr. Horror and ... and ... just go and listen - and go halfway down the page).
I just love Joss Whedon.
