Philip Winchester plays Peter Stone, Deputy Chief of the Special Prosecutions Bureau in the Cook County State's Attorney's Office, on the NBC drama "Chicago Justice."

Growing up in Montana with an American father and British mother, Winchester has a place in his heart for both sides of the Atlantic. As a teenager, he decided to devote himself to acting and moved to the U.K. to train in his craft. He was accepted to the prestigious London Academy of Music and Dramatic Art, all the while helping with his grandmother's bed and breakfast inn outside London.

After graduation, Winchester quickly landed two key roles. The first was in the sci-fi adventure "Thunderbirds," starring Bill Paxton, Anthony Edwards and Ben Kingsley and directed by Jonathan Frakes. In 2007, he played villainous Edmund in the Royal Shakespeare Company's "King Lear," in the seminal production by Trevor Nunn and starring Ian McKellen.

Winchester was cast in the title role of NBC's miniseries "Crusoe" in 2008, based on Daniel Defoe's novel. In 2010, he was cast in an extended arc on "Fringe" as a scientist and love interest of Anna Torv's character. In 2011, Winchester starred as King Arthur's trusted friend Leontes in the series "Camelot," with Joseph Fiennes, Eva Green and Jamie Campbell Bower. In 2015, he wrapped filming five seasons overseas as one of the leads in the Emmy Award-nominated drama-action series "Strike Back," which was Cinemax's first original primetime series in more than 15 years. Also last year Winchester starred in the role of Alex Kane in the NBC drama series "The Player."

Winchester currently lives with his wife and daughter in Montana.
