If you study that closely you will see that there is no such compass direction as "North by North-West". Which may puzzle Alfred Hitchcock fans.
The film title comes from the fact that Cary Grant's character took a flight going North, on Northwest Airlines. Hence "North by Northwest".
Au contraire Mr Trousers. North by North West is compass point number 30 of 32 when looked at like a clock.
