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 Nazis persecuted those they considered to be racially inferior. Nazi racial ideology primarily vilified Jews, but also propagated hatred for Roma (Gypsies) and Black people. The Nazis viewed Jews as racial enemies and subjected them to arbitrary arrest, internment, and murder. Roma were also singled out on racial grounds for persecution. The Nazis viewed Poles and other Slavs as inferior, and slated them for subjugation, forced labor, and sometimes death. Jewish prisoners received the most brutal treatment in Nazi concentration camps.
