The TV movie, based on the bestselling book Remember the Time, will focus on the last three years of Jackson's life, as told through the eyes of his two bodyguards, Bill Whitfield and Javon Beard.
Jackson's 18-year-old daughter Paris previously voiced her distaste for the now-canceled episode of Sky Arts' Urban Myths series centered on a road trip Jackson, Elizabeth Taylor and Marlon Brando reportedly took. Paris took issue with Joseph Fiennes' portrayal of Jackson, calling it "shameful." She has kept silent on Lifetime's upcoming movie, and while she has been invited to the set, Paris hasn't visited.
"I have spoken to the family in the past, but I haven't spoken to them about this project," Navi admitted. "But I believe that when this project is out, they will know it is a fair and true portrayal."
