Portrait of a Lady on Fire (2019)

French historical drama in which an artist (Noémie Merlant) on a remote island in Brittany falls impossibly in love with her aristocratic muse (Adèle Haenel), written and directed by Céline Sciamma.
On a remote island off Brittany at the end of the 18th century, artist Marianne (Noémie Merlant) is commissioned to paint the wedding portrait of Heloïse (Adèle Haenel). The headstrong Heloïse is not keen on the marriage, so Marianne paints the portrait without her knowledge. During long walks on the French coast, she observes her model closely: her movements, her gaze, a rare smile. At night, Marianne secretly works on the painting. In Heloise's last days of freedom the attraction between the two women grows until finally love ignites.
