First Published: October 29, 2011 11:51 AM EDT Credit: ABC Caption Kristin Bauer van Straten as Maleficent in Once Upon A TimeLOS ANGELES, Calif. -- She plays the blood sucking vampire Pam on True Blood, but this Sunday night, Kristin Bauer van Straten has a new nemesis to tackle, as she heads to ABCs Once Upon A Time and it isnt a fairy named Sookie. As Sleeping Beautys Maleficent, Kristin is set to match wits with an equal Lana Parrillas Evil Queen. The Evil Queen needs to do evil and here and there she has to get the ingredients for this evilness and shes got this frenemy, Maleficent, and theyve been kind of helping each other and playing this chess game for years, Kristin told AccessHollywood.com of how she figures into the freshman dramas second episode. She needs a little bit of help to really wield her power, so shes gotta be able to figure out how to get that from Maleficent. Kristin explained that the Evil Queen will need her characters help after the plot twist in Episode 1 that sent a baby Emma Swan (Jennifer Morrison) into the real world. [At] the end of the pilot, [Snow White] has her baby and she puts it in a wardrobe and the baby is safe and thats where, then, the Evil Queen comes to me and shes gonna take it a step further because now shes really pissed, Kristin explained. The actress headed up to Canada to film her so-far one-episode arc and she said putting on the regal gown and headdress was a magnificent experience. [Ive gotten] a lot of help from costuming in the last couple years, she giggled. Theres no way to not feel slightly evil putting on this purple robe and holding a staff, with an orb. I just loved it, Kristin said of her Once Upon A Time costume. I started walking around the wardrobe room already like figuring out. It just gets in your body. Its unbelievable how much help you get from getting dressed up and looking like somebody else. Beyond Once Upon A Time, the actress and activist (shes currently working on a campaign to protect chimpanzees click HERE for more information) is heading back to the set of True Blood shortly for Season 5, where fans will finally learn about Pams back story. The door is open and it would be really fun to come back [to Once Upon A Time]. So well see because Im kind of back in the Pam world and its going to be amazing, she said. I just read the first script. I cant wait to find out more about Pam and I cant wait to actually keep investigating this world and see how they weave this storytelling and these fairytales and these iconic characters together, she added.
