Who would you cast as Buffy if you were casting now?

That's a really hard question. For me, the joy of casting is discovery. The least favourite part of the job is making a list of people who are already known.

Even when I'm working on a thing now, if somebody comes to me and says, "Can you do a list," I so enjoy the process that I almost have a negative knee-jerk reaction to doing it that way. Yes, those people might be on the list, but let's find someone new.

Fortunately, working at Fox Network - as opposed to doing movies, or even some other networks - [is that] they really invest in the discovery of talent and making stars, so I have so much fun there. That sounds easy to do, but boy...

What Sarah, what all those people brought to those roles, it's remarkable. It's a tribute to their talent and Joss's creative skills. It's hard to imagine slotting anyone that I know of now into those roles, they have so made them their own.
