Curiosidades

The script drops hints that Heathcliff is really Earnshaw's illegitimate son, either by a mistress or a prostitute, and thus is Cathy's half-brother. While many critics over the years have debated an incestuous subtext in the novel, this was the first film version to be (relatively) open about the issue.

Oliver Reed briefly sought the lead role.

Like O Morro dos Ventos Uivantes (1939), this film depicts only the first 16 chapters concluding with Catherine Earnshaw Linton's death, and omits the trials of her daughter, Hindley's son, and Heathcliff's son.

AIP had announced a sequel, "Return to Wuthering Heights", but it was not made. Neither were other adaptations of classic novels mooted by the studio, including "Camille", "The House of Seven Gables", and "A Tale of Two Cities."

Judy Cornwell , seen here as the sympathetic housekeeper Nellie, would be featured in a screen version of another Brontë sister's work, playing the villainous Mrs. Reed in Jane Eyre (1983), which starred Timothy Dalton as Rochester.
