(CNN) HBO is standing by its decision to air a four-hour documentary detailing the stories of two men who accuse Michael Jackson of molestation in the face of a suit filed by Jackson's estate that claims airing the film would be a breach of contract.

"Despite the desperate lengths taken to undermine the film, our plans remain unchanged," the network said in a statement to CNN. "HBO will move forward with the airing of 'Leaving Neverland,' the two-part documentary, on March 3rd and 4th. This will allow everyone the opportunity to assess the film and the claims in it for themselves."

The lawsuit, obtained by CNN, cites a contract that HBO allegedly agreed to in order to air a Jackson concert in 1992. (CNN and HBO share parent company WarnerMedia.)

"HBO breached its agreement not to disparage Michael Jackson by producing and selling to the public a one-sided marathon of unvetted propaganda to shamelessly exploit an innocent man no longer here to defend himself," a statement from Jackson estate attorneys read.

The estate argues that HBO had allegedly agreed to "not make any disparaging remarks" concerning Jackson or "any of his representatives, agents, or business practices or do any act that may harm or disparage or cause to lower in esteem the reputation or public image" of Jackson, as part of the contract.
