The series stars Julia Louis-Dreyfus as Christine Campbell, a single mother balancing her work and personal life while maintaining a close relationship with her ex-husband, Richard, played by Clark Gregg.

The show also features Hamish Linklater as Christine’s brother Matthew, Wanda Sykes as her best friend Barb, and Trevor Gagnon as her son Ritchie.

Filming primarily took place in Los Angeles, California, with Andy Ackerman directing all 88 episodes.

She owns a women’s gym and grapples with her insecurities, while striving to maintain some semblance of control over her chaotic life.

She shares a complicated yet cordial relationship with her ex-husband, Richard (Clark Gregg), whose younger girlfriend—also named Christine—is referred to as "New Christine," much to her chagrin.

Christine lives with her son, Ritchie (Trevor Gagnon), and her brother, Matthew (Hamish Linklater), a therapist who often provides sarcastic yet supportive advice.

This includes her ongoing rivalry with the wealthy and condescending "meanie moms" at her son’s private school, Marly Ehrhardt (Tricia O'Kelley) and Lindsay (Alex Kapp Horner), who often exacerbate her feelings of inadequacy.

The series humorously explores Christine's journey through motherhood, friendship, and self-discovery, while highlighting her struggles with modern life and her efforts to rebuild post-divorce.

There are guest appearances from actors including Blair Underwood, Dave Foley, Eric McCormack, Jason Alexander, Jennifer Grey, Jeffrey Tambor, Megan Mullally, Scott Bakula, Ed Begley Jr., Kristen Johnston, Molly Shannon, Andy Richter, Amy Sedaris, Lee Tergesen, Jane Lynch, Marion Ross.

At the conclusion of the season, Christine also becomes engaged to Max, but she feels intimidated by his very educated friends, and also in an effort to improve herself and reach her potential, she decides to return to college.

[5] "While it occasionally runs to the absurd – a blind date who won't eat food other people have touched and brings his own chicken to a restaurant – it stays for the most part within the realm of recognizable human relations, and lets you feel something for its characters.

This was not a luxury Seinfeld ever afforded anyone, and it's nice to see the star getting to play something less cerebrally conceived, less obsessive-compulsive and more ordinarily well-rounded."

The site's critics' consensus reads: "Louis-Dreyfus shines in this well-paced sitcom, making the awkwardness of Old Christine feel refreshingly genuine.

[7] A Los Angeles Times review notes that "Louis-Dreyfus makes Christine feel fresh and real" and the show has a "dry charm and a nice tone of affectionate irony.

Old Christines time slot was changed mid-way through the second season, with a decline in ratings after losing its Two and a Half Men lead-in.
