Los Angeles (CNN) -- Michael Jackson often cried after talking to AEG Live executives as he prepared for his comeback concerts, his oldest son testified Wednesday.
"After he got off the phone, he would cry," Prince Jackson testified. "He would say 'They're going to kill me, they're going to kill me.'"
His father told him he was talking about AEG Live CEO Randy Phillips and his ex-manager, Dr. Tohme Tohme, Prince said.
Prince, 16, began his testimony Wednesday morning in his family's wrongful death lawsuit against Jackson's last concert promoter, AEG Live.
His first 30 minutes on the stand were filled with videos and photographs of Jackson with his children, but then the questioning by Jackson lawyer Brian Panish focused on the last weeks of his father's life.
Michael Jackson, the King of Pop, died on June 25, 2009. Four years after their father's death, Jackson's children -- Prince, Paris and Prince II, aka Blanket -- have stepped into the spotlight to honor their father's memory and create careers and identities of their own. One of the world's first glimpses at the kids was when photographers caught them leaning out of a limousine in Los Angeles in 2000. Here are more moments growing up Jackson:
To protect their privacy in public, Jackson would cover his kids' faces with masks and other obscuring accessories. Here, under the gauzy veils, are Paris and Prince during a trip to the Berlin Zoo in 2002.

Prince testified that Phillips visited Jackson's rented Los Angeles mansion and spoke aggressively to Dr. Conrad Murray the night before his father's death.
"He was grabbing his elbow," Prince said. "It looked aggressive to me. He was grabbing by the back of his elbow and they were really close and he was making hand motions."
He couldn't hear what Phillips was saying to Murray, he said.
Michael Jackson was not there because he was at his last rehearsal, Prince said. He called his father from the security guard shack telephone to let him know Phillips was there. His father asked him to offer Phillips food and drink.
Prince said that was his last conversation with his father.
"Sorry kids, your dad's dead"
Prince recounted the day his father died four years ago. He saw his father "hanging halfway off the bed, his eyes were rolled back," when he ran into the bedroom where Dr. Murray was doing CPR in a futile effort to revive him, he said.
Paris followed him up the stairs, "but we kept pulling her down the stair," he said.
"She was screaming the whole time saying she wants her daddy," he said.
At the hospital later, Dr. Murray told them "Sorry kids, your dad's dead," Prince testified.
Prince was 12 when the pop icon died, but he said his father confided in him about whom he trusted and didn't trust and what he feared as he prepared for his comeback concerts.
Michael Jackson's three children -- Prince, Paris and Blanket -- and their grandmother Katherine Jackson are plaintiffs in the lawsuit, which contends AEG Live is liable in Jackson's death because the company hired, retained or supervised Murray, the doctor convicted of involuntary manslaughter.
Murray told investigators he gave Jackson nightly infusions of the surgical anesthetic propofol to treat his insomnia. The coroner ruled the singer died of an overdose of the drug.
AEG Live executives allegedly created a medical conflict of interest that pressured Murray to pursue the dangerous treatments so Jackson would be rested for rehearsals, while ignoring warning signs that his health was failing, Jackson family lawyers argue.
AEG Live lawyers contend that it was Jackson who chose and controlled the doctor and that company executives had no way of knowing what treatments Murray was delivering.

AEG Live lead lawyer Marvin Putnam's cross-examination of Prince lasted just 25 minutes. It centered on trying to discredit his testimony about Phillips' visit to his home and about cash payments that Prince said his father gave Murray at times.
Prince stood by his story about the Phillips and Murray encounter, although he conceded it could have been two nights before his father's death and not the last night.
The toll of losing their father
Prince's testimony gave Jackson lawyers a chance to show jurors the emotional toll suffered by Jackson's children, which they would have to put a dollar figure on if they conclude AEG Live is liable in their father's death.
"I can't sleep at night," Prince said. "I have a hard time sleeping." The death left him "emotionally distant from a lot of people" for a while, he said.
He's missed sharing with his father "the first day of going to school, having the first girlfriend, being able to drive," Prince testified.
While Paris Jackson's suicide attempt and hospitalization was not brought up in court -- and it is unclear if jurors learned about it in the news -- Prince did speak about his sister.
"I think out of all of my siblings she was probably hit the hardest because she was my dad's princess," he said.
Prince said the questioning of Paris by AEG Live lawyers over two days in March was painful for her. "She had some problems before, after and, I assume, during," he said.
"She definitely is dealing with it in her own way," her brother said.
Paris, who was 11 when her father died, is not available to testify in person in court because she is hospitalized for psychiatric treatment.
While he and his sister no longer want to celebrate birthdays because "it's not the same without" their father, Blanket, now 11, does, Prince said.
"Right now, I don't know if Blanket realizes what he lost," he said. "He was so young. He is still growing up just like I am and he doesn't have a father to guide him."
AEG Live attempted to compel Blanket, the youngest child, to testify, but the judge rejected its request after a psychologist said it would harm the boy.
Changing the world?
Jurors watched a home video of Michael Jackson questioning his three children about how they planned "to change the world" when they grow up.
Prince testified that the video was made at Christmas.
"What's Christmas mean?" Jackson is heard asking his children.
"Love," Blanket responded.
"Who's Blanket going to be to change this world?" Jackson asked.
"I don't know," Blanket, who appeared to be about 5 at the time, answered.
"What does Paris want to do? Be honest search your heart," Jackson said.
"Help the poor," she answered. Paris also said she would like to be a gymnast.
Prince told his father he aspired to be a movie director and architect because he liked "making things."
Private details revealed
Prince, who said his grade point average is 3.68 at the private school in Sherman Oaks, California, at the end of his sophomore year. He is a member of the National Honors Society and received artistic awards at school, he said.
His extracurricular activities include martial arts and working as a mechanic in his school's robotics program, he said. He wants to attend the University of Southern California to study film and business, he said.
His father taught him how "the great ones" made movies, including how to "find shots." He gave him a lens that hung on a necklace that showed what a shot would look like, he said.
Prince said while his school requires a certain amount of community service, he's does more than that. He volunteers at Children's Hospital in Los Angeles in a program that delivers books to young patients "to keep their minds off their problems."
His father "always said you should give back to the community and help out as much as you can," Prince said.
The jury was shown video of Jackson and his children at the Neverland Ranch where they lived until moving after Jackson was acquitted in a child molestation trial.
The family moved after the court case "because there were complications," Prince said. "They ruined it for my dad."
One video showed a giraffe and several alpacas in the Neverland Zoo. "I never really went near them because they would spit on us," Prince said.
The video also showed the carnival rides at Neverland. "We only went there and to the zoo on special occasions because my dad wanted us to remain humble," he said.
When shown a photo of his father sitting with him at a piano, Prince said "I can never play an instrument and I definitely can't sing."
The trial is in its ninth week and is expected to last until August.
