Netflix is said to be issuing warnings on 'The Crown' season 4 due to the depiction of Princess Diana's bulimia.
The Princess of Wales will make her debut appearance on the next season of the historical drama.
Actress Emma Corrin is playing her.
The series will portray Princess Diana developing the eating disorder after getting engaged to Prince Charles, played by Josh O'Connor.
She is seen becoming increasingly unhappy as she moves into Buckingham Palace. Moreover, her marriage starts falling apart.
The Sun reports that three of the ten episodes of the series will carry viewer discretion warnings to warn of vomiting scenes.
The warning reads: "The following episodes includes scenes of an eating disorder which some viewers may find troubling. Viewer discretion is required."
A TV insider said: "This is an unprecedented move by the creators of the drama. After all, it has previously featured scenes of war, a suicide bid, and will even include a terrorist attack in the new series.
"But they have never chosen to issue a warning over these potentially disturbing images. It’s a reflection of how explicit the imagery is and how sensitively they are treating it."
A Netflix spokesperson stated: "'The Crown' producers worked closely with the eating disorder charity, BEAT, to ensure that their portrayal of Princess Diana’s bulimia was both accurate to the disorder and sensitively handled, and when viewers watch the series on Netflix they will see warning cards at the beginning of the episodes giving details of how to seek help if required."
Season 4 will cover the years 1979 to 1990.
It hits Netflix on November 15th.
