Agent, business manager chart Johnny Depp's rise and fall

WARNING: This story contains details of intimate partner violence.

Three people who were once close to Johnny Depp on Thursday charted the actor's rise and fall from "the biggest movie star in the world" to a man who struggled with drugs, money and the ability to show up at movie sets on time.

Testifying at the behest of attorneys representing Depp's ex-wife Amber Heard were a longtime agent, a former business manager and a friend of Depp's for nearly four decades.

Tracey Jacobs, who served as the actor's agent for about 30 years, said Depp was "showing up late to set consistently on virtually every movie" during their final years working together.

"I was very honest with him and said, 'You've got to stop doing this — this is hurting you,"' Jacobs said during a previously recorded deposition that was played in court Thursday. "And it did."

The testimony served to push back against Depp's libel lawsuit against Heard. Depp claims that a 2018 op-ed piece Heard wrote in the Washington Post unfairly portrayed him as a domestic abuser and cost him a lucrative Hollywood career that included the Pirates of the Caribbean movie franchise.

Heard's attorneys argue that Depp's professional undoing was the result of his own bad behaviour.

Depp says he never struck Heard and that he was the victim of abuse inflicted by her. Heard's attorneys say Depp did physically and sexually assault her, and that his denials of abuse lack credibility because he frequently drank and used drugs to the point of blacking out.

Jacobs said Depp was an extraordinary talent who went on to become "the biggest movie star in the world." But his behaviour in the years before he fired her in 2016 became increasingly unprofessional, while his drug and alcohol use increased, Jacobs said.

"And it also got around town," Jacobs said. "I mean, people talk, it's a small community. And it made people reluctant to use him."

Success changed Depp's lifestyle

Joel Mandel, Depp's former business manager, testified in a previously recorded deposition that the Pirates of the Caribbean films had "catapulted him into an entirely different level of success."

"It meant more employees," Mandel said. "It meant buying additional property. It meant a bigger life and a more expensive one."

Things began to change around 2010, and it "became clear over time that there were issues with alcohol and drugs," Mandel said. "And that translated into more erratic behaviour, more stressful behaviour, more times when it was difficult to engage in the kinds of conversations I needed to do my job."

At one point, Depp was spending around $100,000 US a month for a doctor and staff to help him get sober, Mandel said. At another, he was spending $300,000 a month on full-time staff, he said. And he said there also were times when Depp spent thousands of dollars a month on prescription drugs.

"The spending levels had grown very, very, very large and required that level of incredibly high income to be maintained," Mandel said. "And when it dropped off, the disconnect became untenable."

Mandel said he became extremely worried about Depp's finances in 2015, but that Depp met those concerns with anger. He said the actor fired him in 2016.

Depp could be jealous in relationships: former friend

Bruce Witkin, a musician who was friends with Depp for nearly 40 years, testified in a previously recorded deposition that Depp could become jealous in his romantic relationships.

That jealousy was demonstrated with Heard when she would be off filming a movie "or doing something that he couldn't be around to see what was going in," Witkin said. "I think he would work himself up."

Witkin said he once saw bruises on Heard's arm when he and Depp were working on a documentary about Rolling Stones guitarist Keith Richards. And he saw Depp with a "fat lip" one time. But Witkin said he never saw Depp or Heard physically abuse each other.

Witkin said he tried to help Depp with his substance abuse and had set him up with a therapist.

"He'd say, 'I'll be all right. I'll be all right,'" Witkin said, recalling a conversation. "Well, you're not all right."

Depp's sister, Christi Dembrowski, was always concerned with his well-being, both in terms of his substance abuse and generally, Witkin said.

"Everybody, I think, deep down inside was, but ... the people on the payroll won't really say much. They'll try but they don't want to lose their job," Witkin said. "I'm not saying they all fall into the category. But it's a strange thing around people like him. Everybody wants something."

Witkin said his friendship with Depp began to dissolve toward the end of 2017, when the actor started to pull away.

"He wrote me this weird text saying I stabbed him in the back and badmouthed him," Witkin said. "And I'm like, 'What are you talking about?' And he wouldn't explain it. And I pretty much haven't seen him since 2018."
