The "Oslo Trilogy” is a loose thematic grouping of films by Joachim Trier, consisting of Reprise (2006), Oslo, August 31st (2011), and The Worst Person in the World (2021). While not connected through a continuous narrative, the three films are united by their setting in Oslo and their focus on contemporary urban life, often following young adults navigating identity, relationships, and the search for meaning, with a strong emphasis on character psychology and modern existential themes.
