The Godfather (1972)

Francis Ford Coppola's crime saga followed the powerful Corleone family as they navigated the violent underworld of organized crime. And while Keaton wasn't usually the first person mentioned when discussing this film, she was an essential part of its brilliance.

As Kay Corleone, she acted as both a moral anchor and a window into the insular world of the Corleones. Her outsider status gave the audience a way in, while her conscience illuminated what Michael had sacrificed in the name of power.

Looking for Mr. Goodbar (1977)

Based on Judith Rossner's 1975 novel, this Richard Brooks–directed drama followed Theresa Dunn, a schoolteacher navigating a double life in 1970s New York City.

Keaton's performance earned her a Golden Globe nomination, and with good reason. As Dunn, she delivered an unflinching portrayal of a woman seeking freedom, connection, and identity in an unforgiving world.

Reds (1981)

This sweeping historical drama, directed, produced, and co-written by Warren Beatty, told the story of journalist John Reed, who documented the Russian Revolution in his 1919 book "Ten Days That Shook the World."

Opposite Beatty, Keaton portrayed journalist and suffrage activist Louise Bryant with a commanding presence. The role allowed her to channel a fierce energy that mirrored her own real-life passion for causes she believed in.

Father of the Bride (1991)

In this remake of the 1950 comedy, Keaton played Nina Banks, the steady counterpart to her neurotic husband, George, who struggled with the reality that their daughter was getting married.

Coming off "The Godfather Part III," Keaton took on a role that was warm, witty, and refreshingly grounded. She didn't settle for the typical sitcom-style wife. Instead, she gave Nina a calm authority and genuine humor that kept the film emotionally balanced

The First Wives Club (1996)

This sharp, empowering comedy followed three women who joined forces after being dumped by their husbands for younger women. As Annie MacDuggan-Paradis, Keaton portrayed a nervous, soft-spoken wife grappling with betrayal and self-worth.

Her performance struck a chord with anyone who had ever struggled to find their voice. Alongside Midler and Hawn, she brought an irresistible blend of humor, vulnerability, and strength.

Hanging Up (2000)

Based on Delia Ephron's 1995 novel and adapted by both Delia and Nora Ephron, this family dramedy centered on three sisters managing their aging father's declining health and their own strained relationships.

Directed by Keaton, who also starred alongside Meg Ryan and Lisa Kudrow, the film marked Walter Matthau's final screen appearance. While "Hanging Up" didn't receive glowing reviews upon release, it offered a moving portrayal of the messiness and love that define family ties.

Something's Gotta Give (2003)

Nancy Meyers's romantic comedy flipped genre expectations by casting older leads and delivering one of the most beloved rom-coms of the 2000s.

Keaton played Erica Barry, a successful playwright who finds unexpected love after a lifetime of independence. Her chemistry with Jack Nicholson gave the film its charm, but it was Keaton's layered performance that anchored it.

The Family Stone (2005)

This holiday drama followed a close-knit family navigating a tense Christmas gathering with a new, unwelcome guest in tow. As Sybil Stone, Keaton infused the film with depth and emotional honesty.

Her portrayal of a fiercely loving, terminally ill matriarch added resonance to a story that could have easily leaned into snark. Whether defending her gay son or grieving quietly over a photograph, Keaton gave the film its soul.

Because I Said So (2007)

This romantic comedy followed Daphne, a meddling but well-meaning mother trying to help her youngest daughter find the right man — whether she wants the help or not.

Book Club (2018)

In this Bill Holderman–directed rom-com, four longtime friends found their lives upended after choosing "Fifty Shades of Grey" for their monthly book club. Keaton played Diane, a recent widow who — thanks to the group's latest read — rediscovered her confidence and stepped back into the dating world.

With co-stars Jane Fonda, Candice Bergen, and Mary Steenburgen, Keaton helped turn a playful premise into a genuinely heartwarming celebration of friendship, second chances, and embracing joy at any age.

Keaton's filmography is more than a collection of standout roles — it's a testament to a career built on fearless choices, emotional honesty, and an unmistakable sense of style.

Whether she was playing a conflicted outsider, a sharp-witted romantic lead, or a devoted mother, she brought depth and authenticity to every character.
