Would you be interested in books about movies, TV series or film stars?

Hi, I'm a newbie on eBid with loads of books to list. But I'm trying to give priority to subjects where there's likely to be a market. Obviously you enjoy films and TV series but would you be interested in books assocaited with that. for example, filmstar biographies, 'making of' books. biographies of directors and other behind the scenes staff.? Or what about film/series companion books? Just trying to get a feel for what's likely to sell so any advice will be greatly appreciated.
