The film Memento is introduced with its studio logo and title credits for 1.3 seconds each. The first shot is an extreme close-up of a photograph held by the main character, then a tracking shot moves up to his face. Low key lighting and his distressed expression create a sinister tone. Sound includes non-diegetic music during the credits and diegetic camera flashes. It is unclear if the bloodied main character is the hero or villain from this opening sequence alone.
