It is way too early in the am for this but...
IGN: I know you're a big Battlestar fan. Was it great for you to get to work with Tahmoh Penikett?
Joss Whedon: I'm gonna go out on a limb here and tell the truth – I've had a man-crush on Tahmoh since the first episode of Battlestar.
IGN: From the moment he stayed behind on Caprica?
Whedon: I had a feeling about him. I just had a feeling about him. I know, he gave up his seat to Baltar! Not bright, but cute! But no, he just has a presence. Tim Minear watched the dailies and he said, "I can't believe you found this guy. This guy is so hard to find. A leading man that has a real soulfulness and a real unique quality" and I just felt that from Battlestar, and he brought it completely [to Dollhouse]. When I spoke to him, he was the first person to mention Never Let Me Go, the novel, just from hearing the premise of Dollhouse. The beautiful sadness of that novel so suffuses what we're trying to do, and it was so beautiful when he brought it up that I just knew this guy [was right]. And it follows my rule with Nathan [Fillion]. Hire a Canadian! They're gentlemen and they're very tall.
