So I'm sure I'm in minority here...
...but I do love William Hurt as Rochester. I've browsed all the posts saying he hasn't got the looks, or the temper to be Rochester, that he's too bland etc. However, I liked him a lot. He managed to be at the same time sad, brooding, blunt and direct, with a bitter sense of humor and his voice captured his entire conflicted essence. It was low, a bit rough, saddled with past grief and emotion, but saying the most surprising things in an attempt to bring a little life in his existence.
I've read the book a couple of times when I was very young, I don't remember every detail about the characters, just that I was a bit puzzled by Rochester. I'm not sure what I was puzzled about, maybe I was expecting a handsome lead. William Hurt is not handsome as Rochester, but he's charismatic and made me care about the character, maybe more than I cared a long time ago about the same character in the book.
