Céline et Julie vont en bateau (Céline and Julie Go Boating) - 1974

English and Czech subtitles. Céline and Julie Go Boating (French: Céline et Julie vont en bateau) is a 1974 French film directed by Jacques Rivette.
Shot casually in a documentary style, we see a red-haired woman—we will learn that it is Julie (Dominique Labourier)--sitting on a bench in a pleasant but rather non-descript Parisian park. She is reading a book, we can see, on magic incantations. But after a few minutes of random looks around the park—children playing, a cat on the prowl for pigeons—Julie is suddenly taken by the sight of a lithe woman woozily staggering across the park, a long scarf dangling from her neck. No one else seems to notice the dazed woman when she drops that scarf except for Julie, who leaps up from her park bench. She calls after her. Julie will chase after Céline (Juliet Berto), at first seemingly only on the mundane task of returning a dropped scarf. But with just that simple act, the magic of the narrative—both of this particular story and, in Rivette's meta-approach, that of cinema itself—begins.
The film won the Special Prize of the Jury at the Locarno International Film Festival in 1974 and was an Official Selection at the 1974 New York Film Festival.
