“The Other” — the directorial debut of Charlotte Dauphin, producer of Mia Hansen Love’s “Bergman Island” and “Maya” — is an intimate portrait of a woman’s mental distress as she drifts between dream and reality after experiencing loss. Marie (Astrid Bergès-Frisbey, “The Well-Digger’s Daughter”) is a young ballet dancer with the Paris Opéra. After the sudden death of her father on her 30th birthday, she decides to abandon her artistic career and pursue a reclusive existence. Her grief makes Marie live encased in her own memories and thoughts, obsessing over the mysterious writings left by her father in the family house. Only her love for Paul, a photographer who took the last portrait of her father — captured just before his death — has the potential to reawaken a vital force within Marie and help her evolve into another version of her grief-stricken self.
