Every version of "Four Feathers" as a movie which has been made, so far, has been primarily a war movie. I think that some clever person could completely re-interpret the book and make it into a mystery, with Jack Durrance as the main character - the blind sleuth. Unfortunately I think I'd have to write out the entire movie and book for you, here, in order to make this observation clear, so just you go ahead and experience them for yourselves. Now, so that we can talk about it! :)
