The document summarizes three film trailers: 1) 127 Hours uses clips from the film out of order and voiceovers from the film instead of a narrator. Music focuses on the soundtrack rather than lyrics. 2) Into the Wild uses key scenes and lines with a voiceover to explain the story. Music fits the mood and imagery. Text is limited but provides credits and release details. 3) Touching the Void uses significant clips without a narrator, instead using interviews and documentary audio/video. Music is almost non-existent to maintain realism, using diegetic sounds like nature instead. Text is only used minimally.
