Lexa Doig (“Stargate: SG-1,” “Continuum”) has been cast as Talia al Ghul in The CW and DC Entertainment’s “Arrow” TV series.
The casting finally fills the last of the family line with Matt Nable having played immortal villain Ra’s al Ghul in the third season and Katrina Law having taken on the role of his other daughter Nyssa who has recurred on the series since the second season.
This incarnation of Talia is described as: “worldly and cultured, and an elite warrior who doesn’t pick sides but rather creates her own.” Doig will appear in multiple episodes starting with the tenth of the current fifth season.
A young version of the character appeared briefly in an episode of “DC’s Legends of Tomorrow”.
