The former Det. Javier Esposito will play Mike, co-worker and best friend of Milo Ventimiglia’s Jack, our sister site Deadline reports.
The upcoming drama follows a group of people — including Jack — who share the same birthday and whose paths “intertwine in curious ways” (per the official synopsis). The series also stars Mandy Moore (Red Band Society), Chrissy Metz (American Horror Story), Susan Kelechi Watson (The Blacklist), Sterling K. Brown (The People v. O.J. Simpson), Ron Cephas Jones (Mr. Robot) and Chris Sullivan (The Knick).
In addition to Castle, Huertas’ past TV jobs include roles on Without a Trace; Sabrina, the Teenage Witch; The Shield; Undressed and Moesha.
This Is Us premieres Tuesday, Sept. 20, at 10/9c, before moving to its regular 9 pm time slot starting Oct. 11.
