BBC Host: Hello, and welcome to tonight's live chat with Emma Caulfield - Anya in Buffy the Vampire Slayer. Emma is ready to start answering your questions.

Here's the first question.

Jennifer: If you were a vengeance demon, what would you do to who and why?

Emma: Hmm. I probably would find one of my ex boyfriends and kick his a*** - he deserves it.

Mike: You've worked on Beverly Hills 90210 and now Buffy, both huge TV programmes. How different is Buffy to Beverly Hills 90210?

Emma: The hours are a lot longer, it's just a completely different type of genre so there's a lot of expensive make up and time that is alloted for special effects and that sort of thing. Now that I've been in it for so long it all just seems very normal to me.

I have a great time working with the cast of Buffy, it's like a little family. The crew is amazing, we all hang out at work, it's all very friendly and familiar.

90210 was a little bit more rigid, but it had it's moments.

Nathan George: Is the Buffy schedule too hectic sometimes?

Emma: It's only really difficult when we split up the week into day shoots and night shoots. To start off on a Monday at 6am, wrap at 7pm and then as the week progresses the start times get later and later as you're shooting nights.

You could be shooting at 3am in the morning and then go back for a 6am call the next morning, your body gets really confused.

I make sure I sleep as much as I can and relax in the trailer when I get a chance. On the weekends I just try to sleep in and go to the gym and drink a ton of water!
