Looking for Mr. Goodbar is the most unsettling film of Diane Keaton’s 1970s career, and it is unsettling precisely because it refuses to give its heroine an easy explanation. As Theresa Dunn, a young teacher in New York who leads a respectable life by day and seeks anonymous encounters in bars by night, Keaton plays a woman who is neither a victim in a simple sense nor a rebel in a triumphant sense. She is searching for something she cannot name, and the film follows that search without flinching. It remains controversial today, but it also remains one of Keaton’s bravest performances, because she never asks the audience to forgive Theresa in advance.
Theresa is introduced as a capable, warm teacher who works with deaf children, a detail that matters. She is patient, skilled, and genuinely good at her job, and Keaton plays those classroom scenes with a tenderness that establishes Theresa’s competence. At home, however, she lives under the shadow of a strict Catholic upbringing and a family that expects her to be good in a narrower sense: quiet, chaste, and obedient. Keaton shows the pressure of that expectation not through arguments, but through the way Theresa holds herself when she returns home — a little smaller, a little more careful, as if she is already apologising for a life she has not yet lived.
By night, Theresa goes to bars, drinks, and picks up men she barely knows. Director Richard Brooks, adapting Judith Rossner’s novel, does not present these scenes as glamorous or as purely liberating. They are compulsive, lonely, and sometimes frightening, and Keaton refuses to glamourise them. She plays Theresa’s desire as real and urgent, but also as disconnected from tenderness. In the bar scenes, her eyes scan the room with a mixture of excitement and fear, and her laughter often arrives a beat too late, as if she is performing a version of freedom she has not yet learned how to inhabit. That ambiguity is the performance’s centre: Theresa wants to be free, but she has been taught to equate freedom with secrecy, and secrecy with shame.
What makes Keaton’s work so distinctive here is that she never separates Theresa’s two lives into a good self and a bad self. The teacher and the bar regular are the same person, and Keaton lets qualities cross between them. The patience she shows her pupils appears, in a different form, in the way she listens to strangers. The hunger for approval she feels at home appears again in her need to be wanted, even briefly, by men who do not know her. She is not playing a split personality; she is playing a woman whose life has no safe place to be whole. That wholeness is what she is looking for, even if she calls it by another name.
The film’s supporting world sharpens that portrait. Theresa’s family, her colleagues, and the men she meets each offer a partial version of who she should be: the dutiful daughter, the responsible teacher, the desirable woman, the damaged girl who needs saving. Keaton reacts to each of those projections with a slightly different version of herself, and the audience can see the effort it takes to keep those versions separate. It is exhausting work, and Keaton lets that exhaustion show in her face, her posture, and the way her voice grows flatter as the nights go on. By the final act, Theresa is not merely tired; she is hollowed out by a search that has given her attention without intimacy.
Looking for Mr. Goodbar was controversial on release, and it remains difficult to watch, partly because its ending is violent and partly because the film refuses to moralise neatly about Theresa’s choices. Some critics at the time treated Theresa as a cautionary tale, while others saw her as a victim of a society that gave women sexual freedom without emotional safety. Keaton’s performance sits between those readings, which is why it has lasted. She does not play Theresa as a lesson, and she does not play her as a martyr. She plays her as a person making choices that are understandable, risky, and ultimately self-destructive, and she trusts the audience to hold all three truths at once.
For Keaton’s career, the role was a deliberate risk after the success of Annie Hall in the same year. Where Annie Hall used her comic timing and warmth to create one of the most beloved characters of the decade, Goodbar used her seriousness and her willingness to be unlikable. That contrast proved her range in a single year, and it showed directors that she could carry a dark drama without the protection of comedy. She was not simply Woody Allen’s muse or a romantic lead; she was an actor willing to explore a woman’s interior life even when that life was messy, contradictory, and painful to watch.
Seen from today, the film also speaks to the late 1970s in a way that feels historically specific and still relevant. New York in the film is both exciting and dangerous, a city where a single woman could live independently, work professionally, and go out alone, but where independence did not yet come with safety or social support. Theresa’s story is not just about sex; it is about what happens when a woman is given freedom in public and guilt in private, and has nowhere to talk honestly about the gap between them. Keaton understood that gap, and she played it as a lived condition rather than a thesis.
That is why Looking for Mr. Goodbar belongs among Keaton’s signature roles, even though it is not a comfortable film to revisit. It is the role in which she most fully trusted ambiguity. She did not ask for sympathy, she did not offer a redemption, and she did not simplify a woman who could not simplify herself. Theresa Dunn remains, decades later, a haunting figure precisely because Keaton played her as a complete person: intelligent, kind, lonely, reckless, and searching — a teacher by day, a stranger by night, and a woman who deserved a life in which those two selves could finally meet.
