'Arrow' casts 'Riddick' alum as DC Comics villain Ra's al Ghul

Arrow has found its big bad for season three.

Matt Nable (Riddick) has been tapped to play DC Comics villain Ra’s al Ghul on Arrow, EW has confirmed.

Considered to be one of Batman’s greatest enemies in the comics, Ra’s al Ghul is the leader of the League of Assassins and the father of Nyssa al Ghul. Proud and unforgiving, Ra’s is a ruthless strategist, a master of martial arts and a shaper of history. He carries the wisdom of the ages and protects some of its greatest secrets.

Nable, who will recur throughout the third season, will first appear in the fourth episode, “The Magician.”

Ra’s al Ghul was most recently portrayed by Liam Neeson in Christopher Nolan’s Dark Knight trilogy.

Arrow returns Oct. 8 at 8 p.m. on The CW.
