If you loved Pura formalidad, try La desconocida
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 Giuseppe Tornatore, and they both carry the paranoid, slow burn mood tags, and they sit in Drama / Mystery / Thriller territory. If that's the register that drew you to Pura formalidad, the second film will land in a comparable space — through a different lens.

What La desconocida is
Apartments, northern Italy. Winter light, a child's cough. Irena seeks work, any work, to enter a well-off family's orbit. Her motives remain clouded as she manipulates her way into their lives, their home. Tornatore's thriller plays a long game.
