Batwoman Episode 1: Pilot

Kate Kane (Ruby Rose) never planned to be Gotham’s new vigilante. Gotham is a city in despair, the Gotham City Police Department have been overrun and outgunned by criminal gangs. Enter Jacob Kane (Dougray Scott) and his military-grade Crows Private Security, which now protects the city with omnipresent firepower and militia. Years before, Jacob’s first wife and daughter were killed in the crossfire of Gotham crime. He sent his only surviving daughter, Kate Kane, away from Gotham for her safety. After a dishonorable discharge from military school and years of brutal survival training, Kate returns home when the Alice in Wonderland gang targets her father and his security firm by kidnapping his best Crow officer – and Kate’s ex-girlfriend – Sophie Moore (Meagan Tandy). Although remarried to wealthy socialite Catherine Hamilton-Kane (Elizabeth Anweis), who bankrolls the Crows, Jacob is still struggling with the family he lost, while keeping Kate –– the daughter he still has –– at a distance. But Kate is a woman who’s done asking for permission. In order to help her family and her city, she’ll have to become the one thing her father loathes –– a vigilante. With the help of her compassionate stepsister, Mary (Nicole Kang), and the crafty Luke Fox (Camrus Johnson), the son of Wayne Enterprises’ tech guru Lucius Fox, Kate Kane continues the legacy of her missing cousin, Bruce Wayne, as Batwoman. Still holding a flame for Sophie, Kate uses everything in her power to combat the dark machinations of the psychotic Alice (Rachel Skarsten), who’s always somewhere slipping between sane and insane. Armed with a passion for social justice and a flair for speaking her mind, Kate soars through the shadowed streets of Gotham as Batwoman.

Batwoman Cast

Ruby Rose (Orange is the New BlackJohn Wick: Chapter 2) was introduced as Kate Kane/Batwoman in the Elseworlds crossover, before launching into her own Batwoman TV show in 2019. 

“Batwoman is kind of like Batman,” Rose told the New York Times regarding her incarnation of the role. “She’s sort of no-nonsense, very stern. She’s cheeky but she doesn’t speak a ton, and when she does, she kind of does a lower voice, hiding her identity. When I do fight sequences and stunts as Batwoman, I do the Alexander Technique, where we study the bat and study the movement. Even the head movements are kind of batlike, so it feels like two different people.”

Rachel Skarsten, who previously played Dinah Lance (Black Canary) in the short-lived 2002 Birds of Prey series, has been cast as main villain Alice. “If Batwoman had a Joker, it would be Alice, the leader of her Lewis Carroll–inspired Wonderland Gang,” her character description reads. “Swinging unpredictably between maniacal and charming, Alice has made it her mission to undermine Gotham’s sense of security.”

Dougray Scott plays Jacob Kane, the father of Kate/Batwoman; a role that’s being referred to as the male lead in the series, as trades such as Deadline report. Jacob is depicted as a former military colonel who has contempt for vigilantes as he attempts to tackle the crime of Gotham with his private security firm, The Crows. However, in the ultimate irony, he’s unaware that his own daughter has become the very thing he reviles: a vigilante.

The character of Jacob, a fairly recent addition to the canon, was introduced in DC’s Detective Comics #854, dated August 2009. If his television trajectory matches the comics, then the adversarial relationship he has with vigilantes, specifically (his daughter,) Batwoman, is destined to become a partnership, since he is known for utilizing his connections and resources to help in her crimefighting endeavors.  

Meagan Tandy (Teen Wolf) is playing Sophie Moore, described as “After graduating from military academy, Sophie rose through the ranks to become a high-level private security agent and one of Gotham’s staunchest protectors. Despite her bite and regimented outlook, Sophie has a soft side, illuminated by Kate Kane’s return.”

Camrus Johnson (Luke Cage) is Luke Fox, “A Dark Knight loyalist and son of Wayne’s R&D director Lucius Fox, Luke works to keep Wayne Tower secure in his boss’s absence. While Luke considers himself the guardian of all things Batman — specifically his symbol — he also recognizes the city’s need for a new hero.” DC Comics fans will recognize Luke Fox as the character known as Batwing.

Nicole Kang (You) plays Mary Hamilton. “Excitable, talkative, and an influencer-in-the-making, Mary is Kate Kane’s step-sister and polar opposite. But what Mary lacks in a filter, she makes up for with her compassion for Gotham’s underserved communities, proving she has more in common with Kate than she thinks.”

Just two days before the premiere of BatwomanThe Hollywood Reporter unveiled another surprise cast member for the show. MSNBC commentator and host of The Rachel Maddow Show, Rachel Maddow will be a part of Batwoman. Maddow will play Vesper Fairchild, a radio personality and host, who also has a romantic relationship with Batman in the comics. Maddow will lend her voice to the character and never actually appear onscreen. A romantic relationship with Batman is probably out of the question since Batman skipped town and more importantly: she’s just a voice.

“We consider Vesper Fairchild to be the sardonic Voice of Gotham,” Batwoman showrunner Caroline Dries told The Hollywood Reporter in a statement. “In addition to Rachel’s interest in Batwoman, we thought she’d be the perfect casting choice because her own hard-hitting journalism wildly contrasts Vesper’s penchant for snark, gossip and criticism of female superheroes.”

Batwoman Villain

Rachel Skarsten, is playing Batwoman antagonist Alice, the leader of the Wonderland Gang, recently spoke to TV Line about what to expect from her character, saying: “She is the big bad of the show. She plays the main antagonist. She has a very complex relationship with Batwoman, played by Ruby Rose, and she sort of teeters between sane and completely insane. Which is really fun.”

Skarsten teased that Alice has “an axe to grind with another character on the show,” and also “wants to run Gotham … and bring mayhem wherever she goes.”

“[Alice]’s a great manipulator of people,” Skarsten continued, “and because she can sort of sit between the world of sane and insane, she can appeal to many different types of people. And actually, who she brings on side with her, on the show, is quite interesting.”
