As far as I am concerned, Don Quixote is the most metal fictional character that I know. Single handed, he is trying to change the world, regardless of any personal consequences.
I stopped appearing as Dracula in 1972 because in my opinion the presentation of the character had deteriorated to such an extent, particularly bringing him into the contemporary day and age, that it really no longer had any meaning.
I don't play long parts. They must be short parts, but they've got to be parts that mean something, that matter, where people will notice when I'm on the screen, and people will remember the character after they've seen the film.
