Another crucial change from the book is that bad boy Heathcliff, while described as ethnically ambiguous and “dark” in the novel, is very much a pretty straightforward white Australian Elordi. Fennell says that Elordi most represents the version of Heathcliff she saw in her head when she was 14 and reading the novel for the first time. I can’t quibble too much with that, since Wuthering Heights is squarely in the public domain and film-makers can do whatever they want with it.
