Hackers have once again struck at Hollywood, this time claiming one of the summer’s biggest blockbuster releases — Disney’s “Pirates of the Caribbean: Dead Men Tell No Tales,” the fifth installment in the highly profitable swashbuckling franchise, starring Johnny Depp.

Walt Disney Co. Chief Executive Bob Iger told ABC employees in New York on Monday that hackers have claimed to have stolen a movie and are threatening to release it in segments until their demands, which include a pirate-like ransom paid with Bitcoin, are met.

Iger didn’t identify the movie, and the Burbank-based Disney declined to comment. But a person with knowledge of the situation who was not authorized to comment said the movie that was hacked was the new “Pirates of the Caribbean” sequel.

“Pirates” is set to open nationwide on May 26. The last four installments in the franchise have been huge successes for Disney, collectively grossing nearly $3.73 billion worldwide.
