Trivia

Ann's last words in the film are, "If you send for a doctor, I will see him now." These were writer Emily Brontë's last words before she died; avid reader Truffaut probably used her words in the film as an homage or to compare her to the character of Ann.

According to a radio interview, during filming, actress Kika Markham (Ann) introduced director François Truffaut to her parents, who both worked in the English theater and cinema worlds and to whom she had remained quite close. Truffaut, whose own parents had neglected him, got along so famously with Markham's parents that he cast her father, David Markham, in the role of a palmist in the brief scene in which he reads the two sisters' fortunes. However, when he tells her, while reading her palm "Ah, but there's great danger here... you should take care of yourself," her father's performance so disturbed Markham that her look of distress in the film was real. She would come to interpret this scene as an omen of her later ill-starred marriage to actor Corin Redgrave.

According to Antoine de Baecque and Serge Toubiana's biography of Truffaut, those closest to the director regarded this as the most moving film he ever made, as well as the most visually beautiful.
