Sasha Alexander, who played Special Agent Caitlin “Kate” Todd on NCIS, left the show after only two seasons due to the demanding schedule. The grueling commitment required by the show, which included filming 24 episodes a year for long hours, led Alexander to decide to leave. Despite her departure, she has continued to enjoy a successful career in television and film, with her most notable role being as Maura Isles in Rizzoli & Isles. While her exit from NCIS was abrupt, Alexander’s impact on the series remains significant.
