Megan Boone “The Blacklist”
Boone’s exit was discussed with The Blacklist writers early on, allowing her story to be completed ahead of the season 8 finale. According to Deadline, the actress played Liz Keen opposite James Spader on the long-running NBC show, leaving Spader, Diego Klattenhoff, and Harry Lennix as the remaining original cast members.
After eight years on the show, Boone shared an emotional Instagram statement about her time as Liz.
“This experience has been an entire life within my own life for me. These eight years of playing Liz Keen have helped me better define the world and myself, as she set out to do the same, “Boone wrote in June.
Mark Harmon “NCIS”
Harmon left the hit CBS series after 18 seasons in October, but perhaps not forever. Since the show’s inception in 2003, the star has played the beloved Special Agent Jethro Gibbs. After solving a case, his character got to say goodbye by deciding to stay in Alaska indefinitely.
Even though the star’s departure marks the end of an era, executive producer Steven Binder told PEOPLE in an October statement, “As long-time viewers of the show may have noticed… Never underestimate Leroy Jethro Gibbs.”
Damian Lewis “Billions”
Bobby Axelrod, the show’s star, is leaving. Lewis announced in October that he was leaving the Showtime drama Billions after five seasons.
The actor thanked the network and series co-creators Brian Koppelman and David Levien in a tweet, “It was an honour and a pleasure to play Axe for five seasons alongside some of the smartest, funniest, and most talented cast and crew I’ve ever worked with. I’m going to miss the Billions family.”
Jesse Spencer “Chicago fire”
Spencer explained why it was a good time to leave the NBC drama after 200 episodes as Captain Matt Casey.
Spencer, who has been on the show since its inception in 2012, said he “couldn’t have asked for anything more” on his final day on set, filming a scene on the “burn stage.”
