Product Research - 'Buried'

• Breathy phone conversation makes audience sympathise with the main character, as well as intriguing them further.
• 'I got hit on the head and I blacked out and that's the last thing I can remember' gives the audience background information on the plot without telling us why he's been 'buried' or who did this to him.
• Lack of both diegetic and non diegetic music at the beginning of the trailer creates a sense of realism for the world within the film, which further reiterates the protagonist's panic, however, the music which is used is urgent - screeching violins typical of horror genre.
