Nathan Fillion‘s new TV castle continues to take shape. Afton Williamson (HBO’s The Night Of, Cinemax’s Banshee) has booked a series-regular role on The Rookie, ABC’s straight-to-series crime dramedy starring Fillion as a nascent cop.
According to Deadline, Williamson will play Talia Bishop, a newly promoted training officer who is assigned to work alongside Fillion’s 40-year-old LAPD rookie. As TVLine previously reported, The Rookie is also on the prowl for an actress to play Fillion’s love interest. The character, Lucy Benitez, is described as a Latina rookie in her mid-20s who is intelligent, confident, tough and compassionate.
The Rookie ensemble also includes Eric Winter (Rosewood, Secrets & Lies) as overbearing training officer Tim Bradford.
Fillion’s onetime Castle EP Alexi Hawley will serve as Rookie‘s showrunner.
