The first chapter of Kevin Costner's 'Horizon: An American Saga' is headed to streaming sooner than you might think. 'Horizon: An American Saga — Chapter 1' will hit the streaming service Max on August 23rd. The film was released in theaters back in June, but disappointed at the box office, opening to just $11 million. The release of 'Horizon: Chapter 2' was then put on hold in order to give audiences the opportunity to discover the first installment on Premium VOD and Max. (Chapter 2 was previously supposed to hit theaters on August 16th before being pulled from the calendar.)
