This is the first book-length academic study of Norwegian auteur Joachim Trier's films. The book, written by an author who has followed his work closely for ten years, offers an introduction to all five feature films, from his debut Reprise (2006) to his recent success The Worst Person in the Word (2021). The book investigates the style and themes of Trier's films through a prologue, nine chapters, and an epilogue. The main section of the book looks closely at selected tropes across Trier's films, such as memory, time, and identity, as well as his style and his innovative use of montage, voice-over and settings. The prologue place Trier in contemporary Norwegian cinema and discuss his different inspirations and collaborations. An interview with Joachim Trier makes up the epilogue of the book.
