Before joining the 12th precinct as a homicide detective, Esposito served in the Special Forces and was an officer in the Organized Crime Task Force at the 54th precinct. Alongside his partner Detective Ryan, they work tirelessly with Detective Beckett to solve murders and bring killers to justice. Always ready with a sardonic comment, Esposito is a loyal partner and a dedicated cop. Even in the face of adversity, he’s got his game face on and nothing can break him. He may have a bit of a bromance with Ryan but he considers himself quite the ladies man. Despite his constant wise cracks, Esposito is very intuitive and always recognized the romantic tension between Beckett and Castle.
Jon Huertas' career spans television, film and music. His work on "Castle" has been recognized with a 2012 ALMA Award and a nomination in 2013 for an Imagen Award. He also starred as the outspoken and gritty Sgt. Antonio "Poke" Espera in the highly acclaimed, Emmy-nominated miniseries, "Generation Kill," as well as in a number of other TV series, including "Prison Break," "Terminator: The Sarah Conner Chronicles," "NCIS," "CSI" and "Without a Trace."
Huertas has recently fulfilled one of his many goals...becoming a recording artist. He attributes the ability to create and distribute a project like "Grown & Sexy Music" (his first album) to technology, social media and the amazing evolution of the "independent artist" in the music business. Huertas is also passionate about producing and directing. One of his first ventures was co-producing "The Insatiable," starring Sean Patrick Flanery and Michael Biehn and distributed through THINKFilm. Since then he has been involved in an impressive catalog of projects, from his directorial debut, "Lone", and his current project, "The Box," to Neil LaBute's "After School Special" and acclaimed documentaries like "Sahaya Going Beyond," with Jeremy Irons, "The Hill Chris Climbed: The Gridiron Heroes Story," with Taylor Kitsch, and the documentary feature "Ricky," currently in production.
As a kid, growing up on the east coast, Huertas was a class clown, played on his high school football team, studied martial arts and worked at Sears. After a stint in the Air Force, he packed up and moved to Los Angeles to pursue a childhood dream of becoming an actor. Currently he serves on the board of SAG-AFTRA Hollywood.
