Arrow, The CW's new crime drama series based on DC Comics' Green Arrow, has brought on former Gossip Girl and Melrose Place actress Katie Cassidy to take the female lead.

Stephen Amell stars in this upcoming serialized action adventure as millionaire Oliver Queen, who secretly moonlights as a bow and arrow welding vigilante out to stop crime.

Katie Cassidy will play Laurel, a young legal clinic attorney with past romantic ties to Oliver. In the comic books, this character has her own alter ego known as The Black Canary. It is not clear if Canary will be making an appearance on the show just yet.

Cold Case's Susanna Thompson has been cast as Oliver's mother Moira Queen. The series is being prepped for a fall 2012 debut on The CW.
