Talia Al Ghul is coming to Star City and she will be played by Continuum/Andromeda alum Lexa Doig.
Talia is the daughter of the late Ra’s al Ghul (Matt Nable) and is the half-sister of Nyssa (Katrina Law). Not quite sure if Law will return as Nyssa when Talia comes to town. Oliver should watch his back since he killed her father and Talia is an elite warrior.
Doig is familiar to the DC universe having appeared in Smallville’s tenth season as Dr. Christina Lamell that Tess hired to stop the rapid aging of one of Lex’s clones. Also, Doig is married to Michael Shanks who was Smallville’s Hawkman/Carter Hall.
According to Entertainment Weekly, Doig will first appear in season 5’s tenth episode and will recur.
