Having been most impressed by this ITV production, I wonder if those of you better acquainted with the novel than I could say which, of the many TV and film versions now made, is the most accurate representation of Emily Bronte's original novel?
I must admit that I don't know how you can say that the Olivier 'Wuthering Heights' is the closest to the book as half of the story is missing. In fact, it is probably least like the book than any other version I have seen and I've seen at least four versions. I also felt that Merle Oberon was a little too cold emotionally to play Cathy.
BBC's 1978 Wuthering Heights - BBC [DVDis the closest in script to the novel, though the acting leaves a little to be desired. The next closest is 1998 ITV productionWuthering Heights [DVD] [1999, which I found the most enjoyable and believable, even if Cathy and Heathcliff are a little too old to play teenagers at the beginning.
