Sci Fi Channel reports that Lucy Lawless joins the cast of its original series Battlestar Galactica in the upcoming third season. Lawless will become a recurring cast member, reprising her role as D'Anna Biers in a 10-episode arc. The third season begins production in Vancouver, Canada, in April.
Lawless (Xena: Warrior Princess) first appeared on Galactica in the second-season episode "Final Cut," playing investigative journalist Biers, who arrived on the Galactica to do an expose on alleged crew misconduct that resulted in the death of four civilians. Eventually, the audience learns that Biers is actually one of the human-looking Cylon agents, who was sent to Galactica on a covert reconnaissance mission.
Lawless' second guest appearance will air on Feb. 24 in the episode "Downloaded," which gives viewers their first real glimpse into the Cylon world. (The second half of season two of Galactica premiered Jan. 6.)
Battlestar Galactica, from NBC Universal Television Studio, airs Fridays at 10 p.m. ET/PT.
