Sean: (On his favorite memory of Firefly and Serenity director, Joss Whedon) My favorite moment – and he wasn't on the set - but we were shooting the series and I just remember the time when his first child was born. That's probably – that sort of epitomizes to me how much of a family I feel with these people. To just be on set and get word that Joss had his first child and how moving that was.
Sean Maher: (about Joss Whedon) He's one of the most amazing people I've ever met in my life. He's a genius.
Sean Maher: (about making Serenity) There was a wonderful feeling of redemption, because we've come back with these people, this great reunion, and there was a wonderful energy.
Sean Maher: Initially, I was turned off by the idea of [being in a science fiction project] because I wouldn't want to do science fiction. But it's not really science fiction. It's Joss's version. It almost feels like a post-apocalyptic Western.
