What would you consider movies/books such as Pirates of the Caribbean, Zorro, Plunkett and Mclean, Sleepy Hollow, Robin Hood, First Knight, Count Of Monte Cristo, Three Muskateers? I want to write a book using this genre, but I am not sure what it is, and would like to do some research into how marketable it is before I write the novel. And if anyone has written or read books like this, how marketable are they?
