Hollywood legend Kevin Costner boasts an estimated $250 million (£193m) fortune, a testament to his decade-spanning career as an actor, producer, and director. However, there's a very real possibility that his net worth could take a significant hit.

The star's latest venture is a four-part western film series titled Horizon: An American Saga. Costner, who both stars in and directs the movies, has invested millions of dollars into his passion project.

With the first installment underperforming at the box office, the future of the franchise now appears uncertain. Read on to learn how much the project has cost him so far and why this isn't the first time Costner has risked his own fortune, with mixed results.
