THE FLASH Casts Katie Cassidy As Earth-Two’s Black Siren


Katie Cassidy best known for playing Laurel Lance on Arrow will be heading over to The Flash to play her Earth-Two counterpart.


Earth-Two Laurel Lance is known as the Black Siren but in press screening Marc Guggenheim Executive Producer on Arrow wasn’t giving much away in the way of plot details. DC Canon though has Black Siren being one of the members of the Justice Society (Not League there is a massive difference) and as being the mother of a certain Dinah Laurel Lance.
