This week I watched the 2015 experimental documentary Sitting in Darkness by Graeme Arnfield. The short film was experimental in its form, as it is completely composed of found footage. The film recounts the 2013 events in Canada in which a loud ominous noise was heard roaring in the sky. Recent scientific theories account the sound as a result of geophysics and traveling sound waves from the Earth. Confused residents at the time began uploading onto social media video recordings of the sound and their reactions. Clips of these video recordings make up a large portion of the found footage used in the film. After about halfway through, the film reveals that this trend of uploading reaction videos became very popular that people began creating fake videos to contribute to the buzz and eventually to the mass hysteria. The audience is left wondering whether the footage they had just seen were real or fake all along. In addition to video recordings, other found footage that Arnfield uses include video game graphics, which he layers on top of another to create disorienting and experimental looks. This experimental film incorporates both its form and content in this theme of uncertainty and real versus fake.
