I had the prosthetics on, and I went to my trailer, I looked in the mirror, and I smiled. And I was, like, "This is the character - everything she does is with a smile and a bit of glee and joy." And that's how I created Darla [from Buffy The Vampire Slayer]. Prior to that, I was, like, "I have no idea how to play this 400-year-old vampire from hell!".
