The film was nominated for an Oscar for best picture and director. Hussey missed out on an Oscar nomination herself in a strong year in which Barbra Streisand won the main award for Funny Girl.
But at that year’s Golden Globes Hussey won the award for best new star.
Decades later, she and Whiting sued Paramount Pictures alleging Zeffirelli – who died in 2019 – had encouraged them to film nude scenes despite previous assurances they would not have to.
The pair sought damages of more than $500m (£417m), based on suffering they said they had experienced and the revenue brought in by the film since its release.
But last year a judge dismissed the case, finding the scene was not “sufficiently sexually suggestive”.
In 1977, Hussey had reunited with Zeffirelli for Jesus of Nazareth to play the Virgin Mary, before appearing in Death on the Nile a year later based on Agatha Christie’s novel.
Her roles in early slasher film Black Christmas (1974) and TV film Psycho IV: The Beginning earned her recognition as a scream queen. In the latter, she p[layed Norman Bates’s mother in a prequel storyline.
In later years she also took on work as a voice actress, appearing frequently in video games.
But she did have one final reunion with her former Romeo – as she and Whiting appeared together in the 2015 British film Social Suicide, which was loosely based on Romeo and Juliet, albeit set in the social media era.
