I am hoping to publish a non fiction scientific book about cinema through this website. I have two questions about copyright.
A) i have made reference to well known films, directors and actors, all in a positive light. Will there be any issue with regards copyright using their names?
I would like to use a film still (frozen image) as the cover for the book (The Battleship Potemkin. Released 1925) will there be any issue with using an image as the cover?
