In another thread the example of the Bones vs Fox lawsuit came up and it can serve as a pretty good example at the potential legal fight brewing. With the US utilizing common law, it does not look good for WB/HBO Max. Here's what I stated in a separate thread:
After reading the situation on Bones and Fox it appears that WB biggest obstacle may be defending the fee it negotiated with HBO Max. I think we all can assume that the details of the dealing is going to come out in court and show that HBO Max did not pay a sufficient amount for the rights to stream the content. That actually brings WW84 into question too because even though WB paid 10 million to the lead actress and director, it does not exempt them from paying a sufficient market fee to stream it. This whole situation can cause HBO Max/Warner to have to pay substantial legal fees and lawsuits. The cost could be in the billions just because there are so many films and parties involved.
To add more fuel to the fire the Netflix deal that was killed earlier by WB may also be used as part of defense for punitive damages by Legendary because there was an actual market value already placed on the film for bidding purposes. If the lawsuits really do flood in like we think they are, I don't see how HBO Max can stay afloat and how ATT doesn't get ticked because their debt load will increase with these lawsuits.
