The Apartment (1996)

The Apartment is a hauntingly beautiful romantic thriller about a man (Vincent Cassel, Black Swan) who turns his life upside down when he overhears the melodic voice of his lost love (Monica Bellucci, The Matrix Reloaded) in a crowded café. Gone before he can catch her, he sets out to find her, abandoning his fiancée, his luggage and his promising career.
