Memento (2000)

The 2000 film "Memento" is a psychological thriller directed by Christopher Nolan and starring Guy Pearce, Carrie-Anne Moss and Joe Pantoliano. The film tells the story of Leonard Shelby, a man suffering from anterograde amnesia who goes to find the man who raped and killed his wife.

What makes "Memento" unique is its non-linear narrative structure, in which scenes are shown in reverse chronological order, starting with the ending and working backwards. This is meant to leave the audience in the same state of confusion as the main character, unable to form new memories and having to rely on tattoos and notes to piece together his quest.

The film was critically acclaimed and has since developed a cult following and is often cited as one of the best films of the 21st century.
