One of the most inventive puzzle-plot movies in quite some time, Memento   is a dark yet playful exercise in narrative structure and visual style. Guy      Pearce stars as a man determined to avenge the murder of his wife.               Complicating his mission to an impossible degree is an unusual affliction: a   rare form of amnesia that prevents him from forming any new memories. Tattoos  and notes keep him somewhat on track, but every person he meets represents a   possible deception or betrayal. With Carrie-Anne Moss and Joe Pantoliano. "An    engaging brainteaser" (Dave Kehr, CitySearch).                           Christopher Nolan---USA---2000---116 mins.
