Last Year at Marienbad (1961)

Alain Resnais' enigmatic masterpiece, a hallmark of the Nouvelle Vague, takes place in an old-fashioned luxury hotel where a mysterious stranger tries to convince a married woman to elope with him, claiming that they had an affair the previous year in the same château. However, as she struggles to recall that supposed romance and the two wander the labyrinthine corridors, an ambiguous exploration of memory and desire blurs the boundaries between past and present.
