'Primer' 2004

Primer is a 2004 American science fiction film about the accidental discovery of time travel. The film was written, directed, produced, edited and scored by Shane Carruth, who also stars. SCENE: Opening (https://youtu.be/ndHgNUuLKIM) Primer is of note for its extremely low budget, experimental plot structure, philosophical implications, and complex technical dialogue, which Carruth, a college graduate with a degree in mathematics and a former engineer, chose not to simplify for the sake of the audience.[4] The film collected the Grand Jury Prize at the 2004 Sundance Film Festival, before securing a limited release in the United States, and has since gained a cult following.[5]
