Coherence is a 2013 American surreal science fiction psychological thriller film directed by James Ward Byrkit in his directorial debut.[2] The film had its world debut on September 19, 2013, at Fantastic Fest and stars Emily Foxler as a woman who must deal with strange occurrences following the close passing of a comet. Byrkit came up with the idea for Coherence after deciding that he wanted to test the idea of shooting a film ”without a crew and without a script”. He chose to shoot in his own home and developed the film’s science fiction aspect out of necessity, as he wanted to ”make a living room feel bigger than just a living room”. While Byrkit did have a specific idea for how the film would unfold, he selected improvisational actors and gave them the basic outline of their characters, motivations, and major plot points.
