I know most of the films changed the novel's plots but The Spy Who Loved Me only used the title, none of the plot in the book was used by the film
Heck, there were a couple times when I had to double check the title that I was in fact reading a James Bond novel, that's how different this one was.
Apparently this was one of Ian Fleming's least favorite of the books he wrote, hence why he only allowed the producers to borrow the name, none of the plot.
