Costa Ronin reprises his role as Oleg Igorevich Burov, who works at the Rezidentura as head of Line X, the KGB's Science and Technology department. His father is a high-level government minister back in Moscow, which provides Oleg with more security and clout than others within the KGB. Oleg is a jovial man, and he assimilates easily; he enjoys the luxuries of American culture. His love affair with Nina brought him in direct conflict with Agent Beeman, and Nina's return to Moscow has devastated him. He and Stan are far from friendly, but they discover that they have a common desire: Nina's safety.
In 2014, Ronin had the pleasure of working with Academy Award® winning actress Halle Berry in the CBS sci-fi thriller Extant in addition to a guest star role on ABC's Marvel's Agent Carter. In 2015, Ronin filmed an episode of Scorpion for CBS and The Player for NBC.
Born and raised on the West Coast of Russia, Ronin developed a passion for sailing at the age of five, a hobby he shared with his father and grandfather. He began exploring his love of the arts and performing at 15 when he began working at a local radio station teaching English to his listeners through music while absorbing American culture through the international radio waves. A move to New Zealand changed his focus a bit as he entered the local university to study International Relations and Political Science.
Not giving up on his artistic aspirations, he immersed himself in training in the performing arts, earning notable roles in a number of local Australian productions. He continued to expand his theatrical résumé with a one-man show entitled The Wall, and starring roles in Traitors, The Visit and Noir. His breakout on-screen role came with the award-winning TV series The Circuit, followed by his feature debut opposite Josh Lucas in Red Dog, Australia's highest grossing film. Ronin will next be seen in the indie film The Midnighters.
In his free time, the Los Angeles resident rides his motorcycle on the city streets and loves to sail and travel the world. Ronin maintains a healthy fit lifestyle practicing CrossFit and hiking the local trails.
