Irréversible is a 2002 French film written and directed by Gaspar Noé. Starring Monica Bellucci, Vincent Cassel, and Albert Dupontel, the plot depicts the events of a tragic night in Paris as two men attempt to avenge the brutal rape and beating of the woman they love. The film is made up of a title sequence followed by 13 segments made to look like long takes. Each of these segments is either a continuous shot or a series of shots digitally composited to resemble a continuous shot. The story is told in reverse order, with each scene taking place chronologically before the one that precedes it.
