Tricia Helfer Powers

TVLine Items: Tricia Helfer on Powers, Reign Casting Shake-Up and More

You can take the sci-fi out of the girl, but you can’t take the girl out of sci-fi.

Tricia Helfer, best known for playing humanoid Cylon Number Six on Battlestar Galactica, has joined the Season 2 cast of Powers, PlayStation announced Tuesday.

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.
