Diane Keaton’s career has never followed a single, predictable line. She moves effortlessly between comedy and drama, warmth and restraint, spontaneity and control, often within the same performance. What makes her truly essential, though, is not just her range, but her ability to make characters feel unmistakably human.
Whether she’s redefining the romantic lead, anchoring a sweeping historical epic, or quietly breaking your heart in a single glance, Keaton brings an emotional honesty that cuts through artifice and lingers long after the film ends. With that in mind, here are her defining projects.

‘Something’s Gotta Give’ (2003)
“I’m not going to be a consolation prize.” Something’s Gotta Give was a smash-hit romantic comedy written and directed by Nancy Meyers, grossing a whopping $266m against a budget of just $80m. While far from Keaton’s most ambitious or intriguing project, her performance in it is still solid, significantly adding to the character. She plays Erica Barry, a successful playwright who unexpectedly falls for an aging bachelor (Jack Nicholson) while recovering from heartbreak.
This is a role that plays to the actress’s strengths. Keaton’s turn here is intelligent, witty, vulnerable, and emotionally transparent. Her natural comedic talents shine through, and she strikes a nice balance between self-aware and physically awkward. She holds her own alongside Nicholson (no mean feat), and the two have an entertaining dynamic: playful, combative, and gradually sincere.

‘Looking for Mr. Goodbar’ (1977)
“You don’t know what it’s like out there.” This lesser-known crime drama from director Richard Brooks features Keaton as Theresa Dunn, a schoolteacher who leads a double life: dutiful by day, immersed in New York’s nightlife by night, searching for connection and escape. The film traces her relationships and emotional struggles as she navigates loneliness, desire, and the shifting cultural landscape of the late 1970s.
Despite being rooted in a very specific time and place, these themes of sexual freedom and vulnerability continue to resonate all these decades later. More than that, Looking for Mr. Goodbar reveals a darker, riskier dimension of Keaton’s screen persona, one that pushes far beyond the warmth and charm she’s often associated with. This is a raw, unsettling, and deeply human performance, messy and complex.
8
‘Marvin’s Room’ (1996)
“Sometimes I think I should have had a different life.” This is a drama about family bonds and long-buried tensions. In Marvin’s Room, Keaton plays Bessie, a devoted caregiver who has spent years looking after her ailing father (Hume Cronyn) and eccentric aunt (Gwen Verdon). When she herself is diagnosed with leukemia, Bessie tries to reconnect with her estranged sister Lee (Meryl Streep).
It’s an ensemble movie with an incredibly stacked cast. In addition to Streep and Keaton, Leonardo DiCaprio, Cynthia Nixon, and Robert De Niro also appear. They’re all impeccable here, helping to ground the dysfunctional family dynamics into something believable and touching. Keaton, in particular, is remarkably subtle in her role, convincing as someone whose identity has long been tied to others. She also has a powerful dynamic with Streep, their relationship strained by old wounds and differing life choices.
7
‘Baby Boom’ (1987)
“I’m not supposed to be doing this.” Keaton leads this one as J. C. Wiatt, a high-powered executive whose life is upended when she unexpectedly inherits a baby. Struggling to balance career ambitions with newfound responsibilities, J. C. relocates to the countryside and discovers a different path that reshapes her priorities. While that premise is a little Hallmark-y, and the themes occasionally come off heavy-handed, Keaton’s charming presence keeps the movie entertaining.
She adds dimension to what could easily have been a stock character. She’s simultaneously polished and commanding as well as ditzy, almost naive, which is a tricky combination to pull off. Her comedic chops carry the film through even its more ridiculous moments. The result is a breezy comedy-drama that’s pretty dated now, but would have been fairly bold and different on release.
6
‘Interiors’ (1978)
“I just want everything to be perfect.” Here, Keaton is one of three sisters (the others played by Kristin Griffith and Mary Beth Hurt) grappling with their parents’ separation and the emotional fallout that follows. They’re a compelling, three-dimensional family, marked by artistic ambition, insecurity, and a ton of unresolved conflict. Through them, the movie makes some incisive observations about fractured relationships and the lingering impact of bad parenting.
In contrast to Keaton’s more lighthearted projects, Interiors is sober, minimalist, and intensely introspective, heavily inspired by the work of Ingmar Bergman. To match that austere tone, the actress delivers a fittingly restrained performance, one that’s very different from her expressive, larger-than-life roles. Her character here operates through hesitation and carefully chosen words. Much of what she feels is implied rather than expressed, roiling just beneath the surface.
5
‘Manhattan’ (1979)
“I think people should mate for life. Like pigeons or Catholics.” Manhattan sees Keaton taking on the role of Mary Wilke, an intelligent, perceptive woman who becomes romantically entangled with a television writer (Woody Allen) navigating a web of relationships in New York City. Shot in striking black-and-white, the film is an intelligent comedy-drama, a meditation on love, ambition, and urban alienation.
In a film obsessed with art, identity, and emotional contradiction, Keaton becomes the emotional anchor, bringing warmth and authenticity to a world that often feels performative and self-conscious. Her character feels real because she’s so full of contradictions. Mary is verbally sharp but emotionally conflicted, confident and insecure, insightful yet self-doubting, independent but seeking connection. The performance is marvelously naturalistic, with Keaton frequently interrupting herself and changing direction mid-thought, emotions surfacing unpredictably.
4
‘Reds’ (1981)
“I’m not interested in being safe.” Reds is a sweeping historical drama chronicling the life of journalist and activist John Reed (Warren Beatty, who also directs and co-wrote the screenplay) and his relationship with writer Louise Bryant (Keaton). Their story plays out against the backdrop of political upheaval during the Russian Revolution. It’s an ambitious movie that falls a little short of its potential, but Keaton’s performance is solid throughout.
Her Louise is many things at once: a writer, a political thinker, a woman searching for meaning. She can be frustrating and impulsive, as well as tough, curious, idealistic, and assertive. Many of her best scenes involve the clash between her beliefs and her lived experiences. No mere love interest, she is driven and relentless, with big plans of her own. Fundamentally, Louise is caught between her ambitions and her relationship with Reed, which makes their chemistry feel volatile and real.
3
‘The Godfather Part II’ (1974)
“I know you don’t love me.” In The Godfather Part II, Keaton reprises her role as Kay Adams, now grappling with the moral consequences of her husband Michael’s (Al Pacino) deepening involvement in the Corleone crime empire. The film interweaves Michael’s consolidation of power with flashbacks to his father’s early years, creating a sweeping exploration of legacy and corruption.
While Keaton’s part isn’t that big, her performance is committed as always. In particular, she does a good job of capturing the growing tension between the character’s loyalty and conscience. Kay becomes a rare point of moral clarity in a corrupt world. She understands what Michael has become and is one of the few characters who refuses to rationalize it. This comes to a head in a big scene where she confronts her husband, making for one of the film’s most powerful moments.
2
‘The Godfather’ (1972)
“That’s my family, Kay. It’s not me.” Keaton’s role in the first Godfather is significantly smaller than the second, but it remains the more essential film in her career because of how much it boosted her profile. Kay is an outsider drawn into the world of the Corleone family through her relationship with Michael. As she witnesses the transformation of a reluctant son into a calculating leader, the story traces her gradual realization of the reality behind the family’s public facade.
Keaton plays the part with sincerity and sensitivity, becoming a kind of moral stand-in for the audience. Through her, we see the initial gap between who Michael is and who he will become. This comes through most strikingly near the end, where Kay asks Michael directly about his actions and he lies to her, cementing the change to their relationship.

‘Annie Hall’ (1977)
“La-di-da, la-di-da.” Keaton delivers her most iconic performance of all here as the title character, a free-spirited singer whose relationship with a neurotic comedian (Allen) forms the heart of the story. The movie charts their romance through a series of memories, exploring the highs and lows of connection with humor and poignancy. Keaton’s portrayal defines the character’s charm, blending spontaneity with vulnerability.
Simply put, this is one of the most distinctive screen personas in film history, rightly winning the star an Oscar. It’s the crystallization of everything Keaton does best: slightly awkward but magnetic, intelligent but uncertain, open, expressive, and unpredictable. In contrast to most romantic leads of the era, who were polished and idealized, Annie is idiosyncratic and evolving. Ultimately, Keaton’s turn as Annie is so natural, specific, and emotionally alive that it reshaped the romantic comedy forever.
