Variety is reporting that The Flash has cast veteran TV actress Vanessa A. Williams (Soul Food, Melrose Place) in the as-yet unnamed role as the mother of Iris West (played by Candice Patton). The character has been alluded to in the show, but no name was ever given.
In comic books, Iris West was adopted and raised by Nadine West, along with her husband Professor Ira West. In The Flash, the CW changed Iris' father to be Detective Joe West (played by Jessie L. Martin).
If this casting report is accurate, this is but the latest addition to the West family in The Flash. Earlier it was announced that Keiynan Lonsdale had been cast as Wally West, the nephew of Iris and -- perhaps more importantly -- Barry's sidekick and eventual replacement in comic books.
The Flash returns with its second season on October 6.
