To get "Horizon" made, the former "Yellowstone" star mortgaged his property in Santa Barbara and invested $38 million of his own money. One industry insider told Business Insider they were skeptical: "He won't lose his house, but he's potentially going to lose a lot of money." Doing the math, that means that for every $10 million "Horizon" makes at the box office, Costner and his investors see $4.6 million back. That means to recoup the $30 million Costner invested in marketing the first "Horizon" movie, it will have to make north of $65 million domestically. AdvertisementBusiness Insider contacted reps for Warner Bros. and Kevin Costner to comment on this story but did not receive a response.
