I know that this is a book blog but with the upcoming buddy read with Nat reminding me of Memento, I thought I would post a little information about it just in case somebody has missed this wonderful film.
Wikipedia does a wonderful job with the description -
Memento is a 2000 American neo-noir psychological thriller film written and directed by Christopher Nolan, and produced by Suzanne and Jennifer Todd. The film's script was based on a pitch by Jonathan Nolan, who wrote the 2001 story "Memento Mori" from the concept. Guy Pearce stars as a man who, as a result of an injury, has anterograde amnesia (the inability to form new memories) and has short-term memory loss approximately every fifteen minutes. He is searching for the people who attacked him and killed his wife, using an intricate system of Polaroid photographs and tattoos to track information he cannot remember.
The film is presented as two different sequences of scenes interspersed during the film: a series in black-and-white that is shown chronologically, and a series of color sequences shown in reverse order (simulating for the audience the mental state of the protagonist). The two sequences meet at the end of the film, producing one complete and cohesive narrative.
Memento premiered at the 57th Venice International Film Festival on September 5, 2000, and was released in the United States on March 16, 2001. It was acclaimed by critics, who praised its nonlinear narrative structure and motifs of memory, perception, grief, and self-deception, and it earned $40 million over its $4.5 million budget. Memento received numerous accolades, including Oscar nominations for Best Original Screenplay and Best Film Editing. The film is now widely regarded as one of Nolan's finest works and one of the best films of the 2000s. In 2017, the United States Library of Congress deemed the film "culturally, historically, or aesthetically significant" and selected it for preservation in the National Film Registry.
It truly is a marvelous movie in just about every department. It also stars Carrie-Anne Moss from "THE MATRIX". If you have never seen this incredible film I urge you to watch it, you will not be disappointed.
