Irreversible’s Director Used A Sub-Sonic Bass To Make Viewers Feel Tense
One of the best ways to affect viewers with a film is by inserting different frames into the movie. In 2012’s Irreversible, Gasper Noe deconstructs a relationship with several graphic and brutal films, making it a really hard movie to watch.
But even though the film was extremely hard, viewers couldn’t really understand why they felt nauseated in certain scenes, including the one when Vincent Cassel is at a nightclub. Apparently, the director inserted a subsonic bass note in some scenes that builds tension and gives an even bigger sense of dread to viewers.
