Variety reports that Jackson’s estate filed a lawsuit against HBO on Thursday, alleging the network will violate a contractual non-disparagement clause by airing “Leaving Neverland”.

The cited clause dates back to a 1992 contract which allowed HBO to run “Michael Jackson in Concert in Bucharest: The Dangerous Tour”.

“HBO and the director were well aware of their financial motives and that ample opposing facts are available from numerous sources, but made the unconscionable decision to bury any evidence casting doubt on their chosen narrative,” the estate’s attorney Howard Weitzman said. “Had they made an objective film it would have allowed viewers to make up their own minds about these allegations, instead of having a television network dictate to them that they must accept these false claims about Michael Jackson.”

The estate is seeking public arbitration to litigate the suit, with claims of damages reaching as high as $100 million or more.
