If you loved La sirena del Mississipi, try Las dos inglesas y el amor
Un puente entre una película que ya has visto y una que casi nadie ha cruzado. Esto es lo que comparten, y lo que la segunda hace que la primera no hace.
Lo que comparten
Both films are directed by François Truffaut, and they both carry the bittersweet, tender mood tags, and they sit in Drama / Romance territory. If that's the register that drew you to La sirena del Mississipi, the second film will land in a comparable space — through a different lens.

What Las dos inglesas y el amor is
Truffaut does his best to film a pre-WWI version of Jules et Jim. A young man becomes involved with two sisters, leading to complicated relationships and emotional fallout. It's the kind of movie where people dramatically run into the sea.
