Kevin Costner, the Oscar-winning actor, has reportedly turned to deep-sea diving in pursuit of treasure and a new hit project, following a controversial article by The Hollywood Reporter. According to a source who spoke to Page Six, Costner is diving in search of sunken riches.

The source revealed that the “Yellowstone” actor recently discovered gold coins and emeralds in the Caribbean. Costner is now pitching a television series centered on finding sunken treasures globally.

Despite his ambitious plans, the insider noted, “No one has agreed to fund it yet,” hinting at Costner’s current challenges within the industry.

The Hollywood Reporter article painted a picture of Costner’s career filled with “a long series of unfortunate incidents,” including disputes, abrupt departures, legal battles, and financial setbacks, with a former colleague describing him as “impossible” to work with.

The THR piece alleged that Costner has had a “long series of unfortunate incidents” in a career “marked by feuds, walkouts, lawsuits, financing fiascos and a growing reputation for being, as one former colleague put it, ‘impossible.’”

Our source said on Tuesday of Costner, “He’s said to be furious over the new Hollywood Reporter story about how he’s lost the plot… He’s very angry about it.”

Costner has allegedly been struggling to finance a series of over-the-top Western movies in his planned four-part “Horizon” franchise, and even mortgaged an unoccupied $60 million oceanfront property in Santa Barbara County to come up with the cash, according to THR.

Perhaps the underwater booty could help pay the bills on the films. (Costner’s “Horizon: An American Saga — Chapter 1” flopped in theaters in 2024, and “Horizon 2” has no current release date. Costner has reportedly been seeking funding on parts three and four.)

Costner has a history of exploring the sea: He has previously said he and an underwater archaeologist, Alex Mirabal — who the movie star met while exploring a Portuguese shipwreck in Mozambique — planned to team up and start an exploration business together, according to an online post.

In March the duo visited the Castillo de la Real Fuerza Museum in Havana, Cuba, to tour its nautical archives which include artifacts from shipwrecks at the end of the 19th century, reports said.

The THR story also alleged that Costner, 70, and his “Yellowstone” co-star Wes Bentley got into a heated physical altercation that left another star, Kelly Reilly, in tears.

Costner, who starred as John Dutton in the Western series, was filming a tense scene with Bentley and Reilly, his on-screen children, on a soundstage in Utah at the time of the alleged altercation.

Sources also told the outlet that certain cast members got fed up with Costner’s “diva-like” demeanor on the show’s set.

Reps for Bentley confirmed the incident but simply called it “a work-related argument during an emotional and physically tough scene,” further saying the matter was “discussed and resolved.” Reps for Costner, whose character was killed off at the beginning of the fifth and last season, declined to comment.

Reps for Costner did not get back to Page Six when we reached out for comment.

Costner starred as a Coast Guard rescue swimmer in the 2006 film, “The Guardian,” and also created the infamous aquatic flop, “Waterworld.”
