According to Newsweek, Anna Faris was only halfway through her contract, which was set to expire at the end of Season 8, when she announced her departure in September. Her upcoming project — Summer Madness, an independent comedy in which she will be playing twins — is still in pre-production, according to IMDb. Summer Madness was announced last year, well before Faris' decision to leave Mom. An anonymous insider revealed to People, "It was a surprise to hear that Anna was leaving... It was sudden and unwelcome, and it left the entire network scrambling."

For the cast, especially co-star Allison Janney, it was particularly upsetting. Janney told Entertainment Tonight, "It's a huge loss for the show to not have Anna because she was part of creating a character, Christy, that everyone fell in love with, who was so lovable and warm and gullible and funny and we will miss her so much."

According to Jaime Pressly, the Season 8 scripts still include plenty of Christy, saying "We still hear the name, we still talk about her. She's not gone as far as we're concerned... so we're happy for her and we miss her no matter what."

Fans will certainly be keeping their eyes open for new projects from the comedic Faris, and thankfully they can still get updates on their favorite character Christy through the storyline of Mom, even if she isn't acting on the show anymore.
