A better lawsuit could be launched by whomever has the copyright protections for the actual documentary. There are large statutory damages alvailable plus attorney fees IMO. This type of suit is beyond my true expertise so I am going by weak memories, but believe I am correct.
Caution: I am a retired lawyer, two years removed from actual practice. These opinions are not professional legal opinions and should be relied upon by nobody. They are offered for entertainment purposes only.
It is also possible that if a particular set of motives can be proven this could involve fruad and securities fraud as well as other securities laws violations; possibly including the commission of criminal acts.
This last post constitutes speculation without full knowledge of facts and with no legal research. Again this is not a professional legal opinion and is offered only for late night entertainment. LOL
