Joachim Trier and Renate Reinsve in Cannes. Miguel Medina/ Norwegian filmmaker Joachim Trier reunites with his Oslo neighbor, acclaimed actor Renate Reinsve for their third collaboration, Sentimental Value, a movie about two bereaved sisters — Nora, a stage actor played by Reinsve, and her younger sibling Agnes, a historian, performed by Inga Ibsdotter Lilleaas — whose estranged father, Gustav Borg (Stellan Skarsgård) a once celebrated movie director, re-enters their lives. Each copes in their own way with generational trauma.
