LIMITLESS is an intense thriller film directed by Neil Burger starring Bradley Cooper, Abbie Cornish, and Robert De Niro. The film begins with a title sequence that provides the production company credits with accompanying sounds that hint at violence. It then shows the main cast names in sync with these sounds. The sequence ends with a voiceover from the main character as he narrates the opening scene, which is revealed to be from later in the film, creating dramatic irony. The film then backtracks chronologically to show the events leading up to this opening scene through a series of shots that build tension and establish the setting and conflict.
