The Rookie series premiere TV billboards...

Throughout his career Nathan Fillion has played a space captain, a mystery book writer, a soap actor and voiced countless cartoon and video game characters, but he may be about to face his toughest challenge yet in The Rookie.

Not to be confused with the 2002 baseball movie, in this crime procedural he stars as 'John Nolan', a 40-year-old man who gives up his comfortable, small town life to move to Los Angeles to pursue his dream of being a police office for the LAPD.

As the oldest rookie on the job, he and his fellow trainee officers patrol the mean city streets of L.A. to keep them safe.

These series launch billboards were snapped along Sunset Boulevard and Melrose Avenue from September 7 to September 22, 2018.

Nathan Fillion starred for eight seasons in the crime comedy drama Castle, so let's see if he can last that long on the beat of his new job.
