IANAL, so I don't know what are the actual legal merits involved in either having a case or not... but if someone came to me about some facts about me that they published, and they wanted me to 'buy the rights' to those historic facts about me, I'd feel totally justified in telling them to piss off. And if I later decided to create any form of written or video story about myself, the peddler who'd come to me earlier would already be on my blacklist of potential partners to work with.
