Variety has learned that The CW is developing a new “Arrow” spinoff that would focus on the crime-fighting team The Canaries.

The show would star Katherine McNamara as Mia Smoak, Katie Cassidy as Laurel Lance, and Juliana Harkavy as Dinah Drake. An episode of the upcoming final season of “Arrow” will serve as a backdoor pilot for the potential series.

Greg Berlanti, Sarah Schechter, Beth Schwartz, Marc Guggenheim, Jill Blankenship and Oscar Balderrama will all be executive producers on the project, with Schwartz, Guggenheim, Blankenship and Balderrama co-writing the episode. Berlanti Productions will produce in association with Warner Bros. Television.

The Canaries are a vigilante group operating in a future version of Star City in which the city was overrun by an uprising by the denizens of the city section known as The Glades.

Cassidy began with “Arrow” in the show’s pilot, though she was killed off in Season 4 before returning in Season 6. She has appeared in multiple other “Arrow”-verse shows as well. On the film side, she has held roles in projects like “Taken,” “Click,” “When a Stranger Calls,” and “A Nightmare on Elm Street.” She is repped by CAA, Anonymous Content and Jackoway Tyerman.

McNamara first joined “Arrow” last season. She was upped to a series regular role for the show’s final season. Her previous credits include “Shadowhunters” and the “Maze Runner” film franchise. She is repped by Atlas Artists, CAA and Jackoway Tyerman.

Harkavy has been with “Arrow” since Season 5 and has also appeared in multiple “Arrow”-verse shows. Her other credits include “The Walking Dead,” “Dolphin Tale,” and “Last Shift.” She is repped by APA and Brevard Talent Group.

It was announced in March that upcoming eighth season of “Arrow” would be the show’s last. The final season will consist of 10 episodes. “Arrow” launched on The CW in 2012 and remains one of the network’s highest-rated shows.
