The cast of the upcoming Batwoman television series has been steadily assembling in recent weeks. Now, one of the stars of 9-1-1 has been cast in a key role.

Deadline reports that Elizabeth Anweis has been cast as Catherine Hamilton-Kane in the CW series. Catherine is the second wife of Jacob Kane and the step-mother to Kate Kane, aka Batwoman. Although the character is a minor player in the comics, the outlet is reporting Catherine will play a significantly more important role in the series.

Reimagined as a defense contractor and one of the most powerful people in Gotham City, Catherine has a dedication towards the city that goes against everything Batwoman is trying to change about the troubled metropolis. Catherine will likely make for a compelling new addition to the show, and add an interesting dimension Kate's mission.

Ruby Rose made her debut as Batwoman during the events of the recent Arrowverse crossover, "Elseworlds." The series will follow her exploits in Gotham City.

Written by Caroline Dries and developed by Bertlanti Productions and Warner Bros. Television, Batwoman stars Ruby Rose, Rachel Skarsten, Meagan Tandy, Camrus Johnson, Dougray Scott, Elizabeth Anweis and Nicole Kang. There is currently no announced release date for the Batwoman pilot.
