The Worst Person in the World (Norwegian: Verdens verste menneske) is a 2021 romantic comedy-drama film directed by Joachim Trier, who co-wrote the screenplay with Eskil Vogt.

While walking home from a publishing event for Aksel, Julie crashes a wedding reception and meets Eivind, a barista.

Julie writes a short story about feminism and oral sex, impressing Aksel, who encourages her to post it online.

She celebrates her 30th birthday at her divorced mother's home, but her father fails to attend, citing back pain.

The website's consensus reads: "The Worst Person in the World concludes Joachim Trier's Oslo trilogy with a romantic comedy that delightfully subverts the genre's well-worn tropes.

"[25] Metacritic, which uses a weighted average, assigned the film a score of 91 out of 100, based on 47 critics, indicating "universal acclaim".

[26] A review on newcityfilm.com called it "a drama in the fashion of a romantic comedy, with serious moments woven with an assured touch into heightened feeling and occasional subjective fantasy".

[28] Richard Lawson of Vanity Fair called it "exquisite, wistful (and downright sad)", praising the cast performances and Trier's writing.

Joachim Trier’s drama about an intrepid and passionate young woman in Oslo reduces her to a handful of character traits.

[...] Trier’s film is set up like a deck of tarot cards, with each scene and event... corresponding clearly to a character trait and pushing a button of pre-programmed emotional response.
