Helfer will play FBI Special Agent Lange, who shares a history (and palpable sexual tension) with Sharlto Copley’s Detective Walker. Lange, who walks a fine line between the Powers world and the government, becomes both an ally and enemy when it best suits her agenda.
Since her BSG days, Helfer has appeared on such series as Ascension, TRON: Uprising and The Firm. Powers is currently in production in Atlanta and will return in 2016.
