Memento features a man; Insomnia ; in The Dark Knight Trilogy Bruce Wayne wants to return Gotham to a time when his parents were alive and is told "you either die a hero or live long enough to become the villain"; The Prestige sees two men spend all their time in competition with each other at the cost of their personal lives and lives; Inception ; Interstellar
Once again in Dunkirk time is not a constant but a storytelling device as Nolan looks at the evacuation of the British troops from Dunkirk beach through three alternating perspectives, each covering a different period of time.
