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.
