The River‘s Paul Blackthorne has been tapped for a co-starring role in the CW drama pilot Arrow, a modern retelling of the story of DC Comics character Green Arrow. It stars Stephen Amell as the vigilante superhero who fights crime using archery, martial arts and technology under his secret identity as Oliver Queen, a wealthy playboy and billionaire industrialist-turned-outspoken politician in Star City. Blackthorne, repped by SDB Partners, Seven Summits & Optimism Entertainment, will play Det. Quentin Lance, the father of Oliver’s love interest Laurel (Katie Cassidy), a gruff, determined city detective who believes true justice can only come from law and order. He’s charged with bringing the vigilante known as The Arrow to justice. Because of his casting being in second position to ABC’s The River, Blackthorne is formally billed as a guest star in the Arrow pilot.
