I'm looking to write a biopic about an obscure historical personality whose story would perhaps still be of interest to people today. The personality in question is so obscure that there is only one biography available, along with a lot of primary sources tucked away out of the public domain (academic institutions, private collections etc), and some online information of variable provenance.
So my question is, if I use the biography as the basis for the majority of the screenplay, does that make it an 'adaptation' by default (and require buying the rights etc)? I assume most screenplays about historical events involve research out of a range of books of history, but in this case there is only one book that I can use for reference, so it strikes me as an unusual situation!
