Written by former Castle executive producer/co-showrunner Alexi Hawley, The Rookie stars Nathan Fillion as John Nolan, the oldest rookie in the LAPD. At an age where most are at the peak of their career, Nolan cast aside his comfortable, small town life and moved to L.A. to pursue his dream of being a cop. Now, surrounded by rookies twenty years his junior, Nolan must navigate the dangerous, humorous and unpredictable world of a “young” cop, determined to make his second shot at life count.

O’Neil will play Lucy, a rookie cop in the LAPD who struggles with a domineering training officer and might be developing a budding romance with Nolan. She joins recently cast Eric Winter and Afton Williamson.

Jones will play Sergeant Wade Grey, the station’s Watch Commander, who becomes a nemesis to Fillion’s forty-year-old rookie.

Williamson will play Talia Bishop, a newly promoted training officer whose first assignment is Fillion’s forty year old rookie. Winter will play Tim Bradford, an overbearing training officer.

Mason will play Capt. Zoe Andersen, Nolan’s confident and irreverent commanding officer.

Mason played the series-regular role of Ofelia Salazar on the first three seasons of AMC’s Fear the Walking Dead. She also recurred on NCIS: Los Angeles and guest-starred on Doubt. Mason is repped by the Gersh Agency and Luber Roklin Entertainment.
