I think that my vampires in general were influenced by my being allowed to watch the Hammer vampire films. Vampire Circus, also shown as Circus of Fear, was one of those movies.
Ultimately you want to do something in life that people will remember. And with Buffy, I did that. I don't feel like I need to achieve something. I just do it because it's fun. And that takes the pressure off.
I'm a religious person. I remember my mom told me: 'Vengeance belongs to God. It's up to him to wreak vengeance.' It's hard for me to get to that point, but that's the work of God.
