Gone Girl is a 2014 American thriller directed by David Fincher and written by Gillian Flynn, based on her 2012 novel. The film stars Ben Affleck, Rosamund Pike, Niel Patrick Harris and Tyler Perry. Set in Southeast Missouri, the story begins as a mystery that follows the events surrounding Nick Dunne, who becomes the primary suspect in the sudden disappearance of his wife, Amy.
The trailer begins at a slow pace, showing an 
establishing shot of a garden to start. The lighting in the frame is very low key and appears to be at dawn or dusk. The trailer continues by playing long/wide and mid shots of a man (Amy's Husband Nick) standing suspiciously outside of a house at the same time of day, he appears alone in the street and very isolated from society. The low key lighting is carried through the first three shots of him, as dialogue of a women voice is used as narrative to introduce the character Nick as "The most hated man in America right now". The woman continues to ask "Did you kill your wife?" this instantly suggests an insight of the storyline to the audience and conveys conventions of crime/thriller trailers. After the question is asked a close up of Nick is shown with a guilty facial expression, suggesting to the audience that he is the protagonist. The trailer then shows a wide shot of him sat in what appears to be an interview and with the women who asked if he killed his wife. Through miss en scene we are able to depict the interrogation interview for example the setting appears to be as though he is on a talk show or being filmed. Both characters in shot appear to be formally dressed wearing a suit and tie and a black dress. The lighting remains low key with only a lamp in the background as a source of light. 
The low key lighting in this shot conveys the mood within the atmosphere coinciding with close ups of sad family members etc. The lighting in the frame places emphasis on the missing persons poster as it appears the clearest/brightest part of the scene.
At 40 seconds in the trailer shots of main actor and husband, Nick, are shown of him in a police station. Mise en scene elements such as costume and props reveal the setting in this scene and conventional police uniform such as police badges, shirts, guns, gloves and swabs creates realism within the thriller as the investigation begins. The low key lighting remains constant throughout the trailer as the plot thickens and the drama begins to build. Although the narrative has clarified Amy is missing from the very start of the trailer, clips of her at home and with Nick are played at the start of the trailer to show equilibrium and how they were together before the disappearance. This allows audiences to relate to their stereotypical heterosexual relationship and therefore builds empathy for the characters when equilibrium is disturbed. In this shot Amy is shown in the Bath, as she is naked, vulnerability and purity is emphasised showing she is an innocent women. Juxtaposition is shown here as she appears to be living a normal life, this contrasts with the storyline of the plot and her disappearance. The next shot shows a close up of her face in the bath still, after her husband walks past the door, the close up shows her sinking down deeper into the bath after being in his presence. The shot fades to black and suggests that time has passed and that things aren't the same anymore, as often trailers appear in non chronological order, or with non continuity editing.
