Inception opening sequence analysis

The opening sequence begins with a quite, beach setting. Children are playing happily in the background of a shot capturing a man lying face down in the waves. The sad non diegetic music that runs parallel, suggests something unnatural or bad may occur. This track juxtaposes the appealingly bright and uplifting colours and highlights the significance on the character lying among the waves, introducing a sense of enigma, why is he there? fully clothed and evidently distressed. A low angle shot is then used to answer this question, stressing the status of a new character, who is holding a gun to the mans back. An establishing, extreme long shot is then used to further set up the scene and location and make this new man, wearing dark, green military attire, connoting assertion and power, seem out of place, mysterious and ominous. This shot then cuts seamlessly to a new location which is previously established from the outside. The lighting is now low key and creates an eerie feel, aided by the shot that leaves a new character unidentified from behind, cast in shadow. This helps to create a tense and suspenseful atmosphere, and further enhances the previous enigma. The camera then focus's on a man at the head of the table who's playing with a thumb tack , an extreme close up shot, further indicates that this object is extremely relevant and important within the sequence. The food and wine in background also develop the personality of this  unidentified character, sat in a dark, ominous environment and yet seemingly feeling right at home and comfortable. Another man is then dragged into the shot, lit by deep, blood red flood lights, that connote danger, hell and horrific circumstances.
