As SXSW this afternoon, geek demi-god Joss Whedon took the stage for a Q&A, first with an Entertainment Weekly writer and then with an adoring audience. The conversation jumped from his films, including the upcoming The Avengers, to his creative process, to Firefly ("I keep thinking they're gonna crunch the numbers and think, oh, we can make money with this! And they don't. I'd never rule it out."), and beyond. @visualhero captured the session as it unfolded.
