Box office tracking for Kevin Costner's 'Horizon: An American Saga — Chapter One' is looking worrisome. The big-budget film is tracking to open to $12 million domestically. That's not great news for Costner and those backing the independently financed Western, considering it cost $100 million to make before marketing and is being followed quickly by 'Horizon: An American Saga — Chapter 2' on August 6th.
