Utilizing the little-known one-in, one-out rule that keeps low-budget genre series supplied with a healthy flow of former Battlestar Galactica performers (the better to draw sci-fi-loving audiences in and keep the streets of Vancouver clear of stray Tahmohs Penikett), Tricia Helfer has been added to the cast of the Playstation Network superhero series Powers. The retired Cylon will play FBI Special Agent Lange, a foil and possible love interest for Sharlto Copley’s former superhero-turned-detective Christian Walker. (She’ll be partially replacing her old BSG co-star Michelle Forbes.)
