TCM showed the long-lost kinescope recording of this live TV performance under its episode title, "Wuthering Heights," on December 6, 2019 - more than 60 years after its only previous broadcast.
In 1999 actress Rosemary Harris met TV historian Jane Klain and asked if she could find a copy of the film. Harris was a last minute replacement and had only 4 days to learn her lines. During the live broadcast she had forgotten the lines before her death scene and had quickly re-read the script and then shoved the script under her pillow. Harris wanted to know if this had been captured in the broadcast. Klain spent 20 years trying to track down a version of the script and finally uncovered it in 2019 after searching for 20 years. She sent a copy to Harris who learned that her re-reading had not been broadcast.
Yvonne Furneaux does not play Cathy. She was fired and replaced by Rosemary Harris.
