Casting for Arrow, the CW pilot based on DC Comics' superhero Green Arrow, continues with the addition of Supernatural and Gossip Girl actress Katie Cassidy. According to Deadline, Cassidy has been cast as Laurel, the show's female lead who is a young legal clinic attorney that has a romantic past with Oliver Queen.
The casting description found on The TV Addict describes the character as "28 years old, smart sexy, Laurel is a legal aid attorney determined to use her life as a one-woman war against the 1% following the death of her younger sister Sara. A sister, who as luck would have it, just so happened to have died aboard Oliver’s yacht."
As fans of Green Arrow know, the character has had a long-running on-again, off-again romantic relationship with Dinah Laurel Lance, a.k.a. the superheroine Black Canary. Cassidy will be the third actress to star as a live-action version of the character for the CW/WB, after Rachel Skarsten appeared as "Dinah Redmond" on the short-lived 2002 series based on DC's Birds of Prey, and Alaina Huffman portrayed the character in a recurring role on the Superman-based series Smallville.
The addition of Cassidy to the Arrow cast follows on news that Stephen Amell will be Oliver Queen/Green Arrow and actress Susanna Thompson will be playing Oliver's mother Moira Queen.
