COSTNER CASH CRUNCH AS MOVIE BOMBS

TV COWPOKE Kevin Costner is facing a nightmare, $100 million bill after his vanity project - Western movie saga Horizon - flopped at the box office, according to insiders who say he's being forced to cash in a trove of precious assets to pay his gargantuan debt.

The 69-year-old Yellowstone stud mortgaged his stunning ten-acre Santa Barbara ranch to help fund the ambitious four-part, bigscreen epic, but the passion project flopped - with the first episode lassoing just $11 million on the opening weekend and the second segment being pulled from its August release.

Now sources snitch he’s going to have to pony up some serious loot.

“Kevin banked Horizon largely on undeveloped California land he owns,” tattles an insider.

“Now reality is starting to set in that he’s likely going to have to part with this real estate and also reshuffle his other holdings to remain solvent after the disappointing showing of the first film.”
