As of now, the character will not appear onscreen, though her voice will appear in multiple episodes.Maddow also shared her excitement on her Twitter account, stating, "I know no one's going to believe this is true, but it's true. I'm 'Vesper Fairchild' in the new Batwoman TV show that starts this Sunday night on The CW. (My character is soooo not me; turns out playing her is one of the most fun things I've ever done)."

"We consider Vesper Fairchild to be the sardonic Voice of Gotham," showrunner Caroline Dries told said 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."

Written by Caroline Dries and developed by Berlanti Productions and Warner Bros. Television, Batwoman stars Ruby Rose, Rachel Skarsten, Meagan Tandy, Camrus Johnson, Dougray Scott, Elizabeth Anweis and Nicole Kang. The series will premiere on Sunday, Oct. 6 and air on Sundays at 8 p.m. ET/PT.
