Memento is the key to Christopher Nolan's obsession with time

Christopher Nolan’s films share familiar elements — Cillian Murphy, a Hans Zimmer score and IMAX-ready spectacle — but the most persistent is his obsession with time. That fixation began with his 2001 breakthrough, Memento, released on March 16, 2001, a neo-noir that remains central to understanding the techniques and themes Nolan has explored for 25 years.

The film opens with a sequence played in reverse: a Polaroid fading and then retracting while blood and a bullet flow backward. Memento alternates two distinct sequences, using black-and-white to show Leonard Shelby sitting in a hotel room and explaining his anterograde amnesia over the phone, while color scenes follow short sequences shown in reverse as Leonard pursues the man he believes killed his wife, John G.

Watching Memento for the first time feels surreal because effect consistently precedes cause.
