It seems that the CW is working on an Arrow spinoff led by Katherine McNamara (Shadowhunters).
The show is based on a continuation of the possible Arrow future timeline that featured an adult Mia Smoak (daughter of Felicity Smoak and Oliver Queen) learning of her family’s past and joining the Canaries, a vigilante group operating in a future Star City.
Katherine McNamara stars as Mia Smoak, Katie Cassidy as Laurel Lance, and Juliana Harkavy as Dinah Drake. 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.
Next month marks the premiere of Arrow’s final season which will be a shortened 10 episodes.
