Laverne Cox already made history, becoming the first openly transgender performer to earn an acting Emmy nomination for her breakout role on Netflix’s Orange Is The New Black. She is now looking to break more ground with the first transgender series regular character on broadcast TV played by a transgender actor.

CBS LogoCox is set to co-star in Doubt, from longtime Grey’s Anatomy executive producers Tony Phelan and Joan Rater, Timberman/Beverly and CBS TV Studios. It centers on a smart, chic, successful defense lawyer at a boutique firm who shockingly gets involved romantically with one of her clients who may or may not be guilty of a brutal crime. Cox will play Cameron Wirth, a fierce and funny, competitive and compassionate transgender Ivy League-educated attorney. The fact that she’s experienced injustice first hand makes her fight all the harder for her clients.

The producers set out to find a transgender performer for the role from the get go.

Cox’s Sophia on OITNB and Jeffrey Tambor’s Maura on Amazon’s Transparent have opened a new chapter for transgender characters on television. On broadcast TV, ABC’s Ugly Betty and Dirty Sexy Money opened the door with such characters several years ago, the regular Alexis Maede, played by Rebecca Romijn, and the recurring Carmelita, played by transgender actress Candis Cayne, respectively.

Cox is repped by Hartig Hilepo Agency and Peikoff Mahan.
