Sentimental Value stars Elle Fanning and Stellan Skarsgård discuss unlikely friendships and avoiding cliche in their new movie from The Worst Person in the World director: "Joachim Trier is not interested in characters that are one-dimensional"

Stellan Skarsgård and Elle Fanning as Gustav and Rachel in Sentimental Value.

Sentimental Value is a film about a family, but it's also a film about a house. In The Worst Person in the World director Joachim Trier's latest, the dysfunctional Borg family and their Oslo home are inextricable from each other – it's been in the family for generations, through the Second World War, death, and suffering, and it takes on the quality of a haunted house. There are ghosts in these walls.

The film follows stage actor Nora (Renate Reinsve) and historian Agnes (Inga Ibsdotter Lilleaas), sisters who are estranged from their father, acclaimed movie director Gustav Borg (Stellan Skarsgård). He left Norway to focus on his career decades earlier after divorcing their mother, but unexpectedly turns up at their mother's wake with two things on his mind: he wants the house back, and he wants to offer Nora a job.
