Joachim Trier’s latest film Thelma, made with his long-term collaborators, writer Eskil Vogt, cinematographer Jakob Ihre and composer Ola Fløttum, marks a new development in the director’s career. His usual powerful existential themes remain, but Thelma represents a departure in other ways, perhaps presaged by Trier’s previous work, Louder than Bombs (2015), which had starred Isabelle Huppert.
