Mark Harmon's role as NCIS Special Agent Leroy Jethro Gibbs began with a guest appearance on the show JAG in 2003, where he was introduced in a two-episode arc. This appearance led to the creation of the spin-off series NCIS, which premiered later that year. Harmon's portrayal of Gibbs, a no-nonsense, highly skilled investigator with a complex personal history, quickly became the cornerstone of the series. His character is known for his strict adherence to rules, often referred to as "Gibbs' Rules," and his deep sense of loyalty to his team. Throughout his tenure on NCIS, Harmon brought depth to Gibbs' character, exploring themes of loss, duty, and redemption. Gibbs' backstory includes a tragic personal loss, which profoundly influences his approach to his work and relationships. This complexity made Gibbs a compelling and relatable character, contributing to the show's success and longevity. Harmon's performance earned him critical acclaim and several award nominations, including six People's Choice Award nominations, with a win for Favorite TV Crime Drama Actor in 2017. His role extended beyond acting, as he also served as a producer and executive producer on the show, influencing its direction and development. In the fourth episode of the nineteenth season, Gibbs' character exited the series as a regular, marking the end of an era for the show. This departure was set in motion by events from the previous season's finale, providing a fitting conclusion to Gibbs' storyline. Despite stepping down from his regular role, Harmon continues to be involved in the NCIS franchise, including narrating and executive producing the upcoming prequel series NCIS: Origins.
