15 TV Shows That Fired a Main Actor and Instantly Improved

Making a TV show is complicated, and good relationships between actors are key to its lasting success. Occasionally, a main actor has to leave a series because of disagreements with the show’s creators or personal issues. While losing a popular actor can sometimes ruin a show, other times it allows the series to improve by bringing in new faces or changing the story’s direction. These changes can actually lead to stronger plots and a better connection between the actors, ultimately breathing new life into the show.

‘Grey’s Anatomy’ (2005–Present)

After an investigation into his behavior on set, Isaiah Washington was let go from the medical drama. His character was written off the show, which gave the character Cristina Yang a chance to grow and become more self-reliant.

‘Lethal Weapon’ (2016–2019)

Look, the show had a rough patch after its second season. They had to let Clayne Crawford go due to reports of a toxic work environment, which is never good.

‘Scandal’ (2012–2018)

After facing personal legal problems that disrupted filming, Columbus Short was removed from the show ‘Scandal’. His character was written off, increasing the challenges for Olivia Pope and her team.

After allegations of harassment led to Jeffrey Tambor’s dismissal, the show’s creators decided to end the series with a musical finale.
