What Memento reveals about human nature, 25 years later

Memento marks the 25th anniversary of its US release this year.

Jonathan Nolan pitched a road‑trip story about a man with anterograde amnesia bent on finding his wife's killer.

Jonathan sent a draft months later; that draft later became his short story 'Memento Mori,' published after the film's release.

Nolan chose to tell the screenplay in reverse and conceived the film as an inversion of Borges's 'Funes the Memorious.'

After exchanging drafts for a year, Newmarket Films optioned the screenplay with a $4.5 million budget; Brad Pitt declined the lead, so Guy Pearce was cast; Carrie‑Ann Moss was cast and suggested Joe Pantoliano.
