Pirates of the Caribbean 5 star Johnny Depp is reportedly a total “nightmare” on set.

Jackie Henderson, host of Australia’s The Kyle & Jackie O show, revealed on her breakfast show that the movie crew has been struggling working with Depp. It was also disclosed that the delays in movie production in Australia were due to the actor’s marital troubles.

“I remember talking to some crew members from Pirates of the Caribbean and they just said, ‘Working on that was a nightmare,’” Henderson told her listeners. She added that the actor would also not show up on set following disagreements with his now-estranged wife Amber Heard.

Henderson’s revelation came up while she and co-host Kyle Sandilands were discussing the news surrounding Depp and Heard’s separation. Reports earlier emerged that  Depp cut off his fingertip in a rage over suspicions that his wife cheated on him. Depp reportedly accused Heard of having an affair with actor Billy Bob Thornton.

Reports indicated that the filming of Pirates of the Caribbean 5 was shut down after Depp injured his hand. The actor flew back to Los Angeles to undergo hand surgery because of the injury. However, Depp reportedly failed to board his scheduled private charter flight back to Australia after he recovered from the surgery.

Depp and Heard earlier sparked controversy after the actress smuggled their Yorkshire terriers Pistol and Boo on a private jet to Australia. Heard was fined for the offense. The couple also made a bizarre apology video for violating the country’s strict bio-security laws.

Is Pirates of the Caribbean 5 going to replace Depp as lead star?

Fans have speculated that the movie might be tweaked so the storyline would focus on Will Turner (Orlando Bloom) instead. Pirates of the Caribbean: Dead Men Tell No Tales will introduce the character Henry Turner (Brenton Thwaites). Henry is believe to be Will Turner’s son.

Pirates of the Caribbean 5 also stars Geoffrey Rush and Javier Bardem. Kaya Scodelario has also joined the cast as astronomer Carina Smyth. She will help Jack Sparrow in his quest to find the Trident of Poseidon. The franchise fifth installment is rumored to cost $320 million.

Pirates of the Caribbean 5 is set to premiere in May 2017.
