Amazon Studios and Gone Girl author-screenwriter Gillian Flynn are done with the cryptic teases and previews (at least for now), offering up not only the official trailer for their upcoming conspiracy thriller Utopia but a premiere date: Friday, September 25. When the conspiracy in the elusive comic “Utopia” turns out to be real, a group of young fans band together to embark on a high-stakes, twisted adventure to use what they uncover to save themselves… and ultimately, humanity.
