Deadline says

One of the highest-profile young lead roles this pilot season has gone to Stephen Amell. In a potential star-making turn, Amell has been cast in the title role of the CW drama pilot Arrow. In the Warner Bros TV-produced project, described as a modern retelling of the story of DC Comics character Green Arrow, he will play 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.
