Reading the book I was struck by how the Count is a threat to the whole of civilization. In the films I’ve seen he is more of a personal threat to those who face him. Possibly I just missed this, or possibly this is how film worked in the second half of the twentieth century.
And now I have some Hammer films of the Count to watch. They are very hard to get hold of, which is a shame as they are such a foundational part of contemporary British culture whether contemporary British culture likes it or not. 😉
