In an unexpected turn of events, Anna Farris has departed her co-leading role on CBS hit sitcom Mom after seven seasons. The series was renewed for two seasons last year, and production on season eight is due to commence next year. According to Variety, Farris had spoken with the producers about leaving the show some months ago to ensure the writers had sufficient time to work on new scripts.

In a statement from Farris, she thanked the cast and crew and pledged to watch the new season when it arrives.

“The past seven years on Mom have been some of the most fulfilling and rewarding of my career. I’m so thankful to Chuck, the writers, and my amazing castmates for creating a truly wonderful work experience. While my journey as Christy has come to an end, allowing me to pursue new opportunities, I’ll be watching next season and rooting for my TV family.”

In a separate statement, CBS had this to say;

"From the inception of Mom, Anna was the first and only choice for the role of Christy. We are so proud of the stories we have been able to tell during Anna’s seven years with us. We wish Anna all the best, and we thank her for her beautiful portrayal.”

In Mom, Farris starred as Christy, a newly sober young mother who is looking for a fresh start in life with her children. However, her path brings her back in touch with her wayward mother (the brilliant Allison Janney), and it's not the easiest of reunions. It remains unclear how Farris will be written out of the show; it also remains to be seen if its loyal fans will tune into a sitcom that just lost the co-lead. Either way, there is a genuine chance that season eight will bring the long-running sitcom to an end.
