The Oslo Trilogy refers to Joachim Trier's three Oslo-set films about bourgeois Oslo natives who are members of the intelligentsia: Reprise (2006), Oslo, August 31st (2011), and The Worst Person in the World (2021). All three films were written by Eskil Vogt in collaboration with Joachim Trier and feature actor Anders Danielsen Lie. The films share a similar milieu and echo each other's themes and images.
