TVLine reports the actress will play Charlotte Dupres in at least five episodes of the show; the character is described as a ‘nemesis’ on the team. Walker will appear in the second half of the sci-fi’s fourth season which will air in April 2013.
Polly Walker is no stranger to the sci-fi genre having played the scheming terrorist Sister Clarice Willow in the Battlestar Galactica prequel Caprica but is probably best known for her role of Atia of the Julii in HBO’s lavish historical drama Rome. Walker’s other notable roles include Waking the Dead, Cane, Sanctuary, Disney film John Carter and the critically acclaimed BBC drama Prisoners’ Wives.
Warehouse 13 has secured several high profile guest stars over the course of its four seasons so far with quite a few hailing from the Star Trek universe. Actors Jeri Ryan, Brent Spiner, Rene Auberjonois and Kate Mulgrew have all appeared in the popular Syfy series.
