The Best Movies About Unconventional and Different Romantic Relationships

What unites these films is what they refuse to do.

Anora won Best Picture at the 2025 Oscars on a $6 million budget. The film centers on a sex worker in Brooklyn who marries the immature son of a Russian oligarch, then watches the marriage unravel inside 48 hours. The award pointed to a question that has held filmmakers’ attention for decades: how cinema handles romances that fall outside conventional dating norms.

The films below cover age gaps, wealth gaps, open marriages, and three-person households. They are among the most-watched and most-debated entries in the category, and several earned critical acclaim alongside commercial returns most studios envy. None of them flatten the relationship into a moral lesson, and almost none give the audience a tidy ending.

That refusal is part of why they hold up across generations that keep rediscovering them through streaming.

Classic Films of Unorthodox Romance

Hal Ashby’s Harold and Maude pairs a twenty-year-old man with a seventy-nine-year-old woman who meet at funerals they both attend for fun. The film flopped on release and earned only $2 million in its initial theatrical run. It later became a cult favorite and now has an 87% score on Rotten Tomatoes.

The pairing was treated as macabre by 1971 critics and reads as tender to current audiences, which says something about how the public mood around age has shifted across fifty years.

Indecent Proposal made $266 million worldwide on a $38 million budget. Robert Redford offers Demi Moore $1 million to spend one night with him while her husband, played by Woody Harrelson, decides what to do about the offer. Critics dismissed the film. Audiences turned it into a hit anyway.

The split between reviewer disdain and viewer demand became the rule rather than the exception for wealth-and-romance plots through the rest of the decade.

The Graduate, with Anne Bancroft opposite Dustin Hoffman, made $104 million on a $3 million budget and earned a Best Director Oscar for Mike Nichols.

Stories of Age Differences

The Idea of You follows a forty-year-old single mother who begins a relationship with a twenty-four-year-old lead singer of a boy band. The film hit number one on Amazon Prime Video during its opening weekend.

Lonely Planet and the latest Bridget Jones film, Mad About the Boy, followed the same template, with older women paired against younger male leads who pursue them rather than the reverse.

Anne Hathaway, Laura Dern, and Renée Zellweger led the three projects.

These films flipped the older pattern on its head, which had usually placed a much older man opposite a much younger woman. An Education, starring Carey Mulligan in an Oscar-nominated turn, fit firmly in that older mold. It tells the story of a sixteen-year-old schoolgirl who enters a relationship with a thirty-something man who turns out to be a con artist.

The Reader, with Kate Winslet in her Oscar-winning role, takes the same gap from the other side. May December collected four Oscar nominations and revisited the territory through a real-life-inspired story about a twenty-three-year age gap that began when one partner was thirteen.

Modern Romance on Screen

The 2018 film The New Romantic follows a college student who decides to date a sugar daddy for a writing project, then finds the line between research and real life blurring. It won Best First Feature at SXSW.

Sugar Daddy, with Kelly McCormack as a struggling musician in a paid relationship, holds a 100% score on Rotten Tomatoes.

Both films appear alongside other stories about wealth and romance. Anora won Best Picture at the 2025 Oscars on a $6 million budget, and Pretty Woman, from 1990, set the template filmmakers continue returning to when exploring love, money, and power dynamics inside romantic relationships.

Cinema’s Take on Polyamory

Design for Living is the earliest mainstream American film to depict a three-person household. A painter and a playwright fall in love with the same woman, who decides she will not choose between them.

The Hays Code forced the studio to soften the implication of the household, but the film still aired the question that polite American cinema had refused to entertain for the prior twenty years.

Vicky Cristina Barcelona earned Penelope Cruz the Best Supporting Actress Oscar for her role as one third of a three-way pairing in Barcelona. The film made $96 million on a $15 million budget.

5 to 7 takes the same theme into a French context. A married woman in an open marriage with her husband begins an affair with an American writer who can only see her between five and seven in the evening, what the French call cinq à sept, the hours their tradition reserves for affairs outside marriage.

Professor Marston and the Wonder Women tells the story of the psychologist who created Wonder Woman alongside his wife and the third partner who lived with them for decades.

Recent Critical Successes

Challengers grossed $95 million on a $55 million budget and brought a tennis-court love triangle to mainstream audiences. Zendaya plays a former player coaching her husband against her former lover, with all three romantically tangled since their teenage years.

The film held the top spot at the U.S. box office for two weekends, with a Trent Reznor and Atticus Ross score that later pulled a Grammy nomination.

Past Lives earned two Academy Award nominations and explores a different kind of unconventional love: two people separated for twenty-four years who reconnect when one is already married.

The Worst Person in the World earned a Best Original Screenplay nomination at the Oscars. It tracks a Norwegian woman across twelve chapters as she rotates between two men and several versions of herself, neither of which fit the romantic script she was handed at twenty.

Poor Things won Emma Stone her second Best Actress Oscar. The story follows a reanimated woman with the brain of an infant as she discovers desire, marriage, and self-determination across a continental tour. The film made $117 million on a $35 million budget.

Each of these recent successes finds its audience by refusing to settle the question of whom anyone should love.

The Pattern Across Decades

What unites these films is what they refuse to do. None of them resolve the central question of unconventional love and the costs that come with it. They show those costs alongside the rewards and leave the verdict to the viewer.

The commercial returns are real. Anora, The Idea of You, Challengers, Vicky Cristina Barcelona, Past Lives, and Poor Things all delivered profits well past the industry norm, which suggests audiences are paying for stories that refuse easy answers.

The films that get made next will keep testing the same territory because the territory has not been fully mapped. Cinema has not exhausted the question of how love forms outside the templates it was handed, and there is still room for one more relationship structure that no major film has portrayed yet.

Someone is already writing it.
