Michael Jackson’s estate has decried a documentary set to premiere this month at the Sundance Film Festival that features two men who say they were sexually abused by the singer.

The 233-minute film, called “Leaving Neverland,” is “yet another lurid production in an outrageous and pathetic attempt to exploit and cash in on Michael Jackson,” the estate said Wednesday.

Hours later, Britain’s Channel 4 and HBO announced plans to air the two-part documentary this spring, following its Sundance debut Jan. 25. In a news release, filmmakers confirmed the film follows two men now in their 30s, Wade Robson and James Safechuck, who say they were befriended by Jackson when they were 7 and 10, respectively. Through what the production describes as “gut-wrenching” interviews with the men and their families, the film will explore how the men came to terms with the alleged “sustained abuse.”

“It took great courage for these two men to tell their stories, and I have no question about their validity,” director Dan Reed said. “I believe anyone who watches this film will see and feel the emotional toll on the men and their families and will appreciate the strength it takes to confront long-held secrets.”

Jackson’s estate is arguing that both men “testified under oath that Michael never did anything inappropriate toward them.
