Johnny Depp's financial and professional standing faced scrutiny as several witnesses shared their testimonies Wednesday in the heated $50 million defamation suit against ex-wife Amber Heard. Witnesses testified to the actor's waning celebrity over recent years in the wake of abuse allegations, poor behavior, and drug abuse.

The actor's former agent, his business manager, and his friend all had their depositions shown in court as they testified to the actor's career over the last 10 years. Heard began dating Depp in 2011, and the couple went public the next year, when she alleges Depp began abusing her physically and subsequently sexually.

Tracey Jacobs is Depp's former agent of 30 years who was fired around the time the celebrity couple split. At the height of Depp's fame, Jacobs referred to the actor as the "biggest star in the world." However, when Depp began displaying "unprofessional behavior," he became a "far more complicated" client, according to Jacobs.

"Well, initially, crews loved him. But crews don't love sitting around for hours and hours waiting for the star of the movie to show up," Jacob said. "It also got around town ... and made people reluctant to use him toward the end."

Soon, Depp began "showing up late to set consistently, on virtually every movie," Jacobs claimed. Eventually, the actor was given earpieces to get his lines fed to him on set. Still, Jacobs testified Depp was never fired from a movie and was paid more than $25 million to be in the fifth installment of the Pirates of the Caribbean series. Disney never committed to casting Depp in the series' sixth film, according to his agent.

"His star had dimmed," Jacobs said.

The actor would also involve Jacobs in his marital problems. When Heard was cast in the film London Fields alongside Billy Bob Thornton, he urged Jacobs to get in touch with the movie's director and producers.

"IT MUST BE SHUT DOWN OR I WILL SUE THEM EIGHTEEN WAYS," Depp wrote in an email to Jacobs that was shown in court.

"I guess he was trying to get me to kill it," Jacobs said.

Jacobs, however, agreed that his reputation was also damaged by Heard's op-ed, among other things.

Joel Mandel, Depp's business manager, was deposed under subpoena. He claimed it became clear to him that Depp had a drug and alcohol abuse problem, which resulted in poor money management. Both Depp's income and spending were "significant."

"My warnings in 2015 that we were in very dire financial circumstances were not met very well," Mandel said.

Mandel was ultimately fired by Depp.

Jacobs also painted a picture of financial woes, testifying that Depp once visited the office asking for $20 million.

A self-proclaimed former friend of Depp, Bruce Witkin, testified further on Depp's drug use, citing the incident in Australia between the actor and his then-wife that left him with a severed finger.

"The fact that somehow his finger got cut off and he's got doctors around him that are supposed to be making him sober. Everything's supposed to be better, and it wasn't," Witkin said.

After Depp's finger was severed, the cause of which is hotly debated, he wrote on walls and mirrors in the house with his blood. One of the phrases he wrote was "easy Amber and Billy Bob," in reference to the London Fields movie.

"He can definitely have a jealous streak in him," Witkin said.
