Representing 9/11: Alejandro González Iñárritu’s short film in 11'09"01: September 11
Published 2011-09-01“…Stressing the fact that the film uses images of the ‘jumpers’ that were widely censored by the media in the aftermath of the 9/11 attacks, it analyses how the director transcends the sphere of representation by deconstructing the viewers’ habitual cinematic experience. As he explores the limits of sight and sound, Iñárritu produces an extremely unsettling viewing experience for his audience who is forced to adopt a type of perception that verges on the traumatic experience and his film can, to a certain extent, be read as staging the return of the trauma of the 9/11 attacks.…”
