This documentary uses a mixture of interviews and reconstruction to tell the true story of the 9/11 terrorist attacks on America. It has a closed, single-stranded narrative structure that answers all audience questions. Interviews are shot in close-up or medium close-up to focus on the emotion and body language of interviewees. Archive images and graphics with interviewees' names and roles are incorporated throughout. A variety of editing techniques, including changing speeds and focus, are used to make the documentary visually interesting. A male voiceover and sad music provide audio that matches the dark subject matter.
