In August 1979, she went missing and was found dead eleven days later in
the back seat of her car, which was parked close to her Paris apartment
in the 16th arrondissement. The police report stated that she had taken a
massive overdose of barbiturates and alcohol (8g per litre). A suicide note
("Forgive me. I can no longer live with my nerves.") was found in her hand, and
"probable suicide" was ultimately ruled the official cause of death by the
French coroner. However, it is often questioned how she could have operated a
car with that amount of alcohol in her body, and without the corrective lenses
she always maintained she absolutely needed for driving. A year later,
her former husband Gary committed suicide.
Seberg was interred in the Cimetière du Montparnasse, Paris, France
Jean Seberg also played Lilith in the movie with the same name (1964). Interesting plot:
Set in a private mental institution, it tells of a trainee occupational therapist Vincent Bruce (Beatty) who becomes dangerously obsessed with a seductive, very able, schizophrenic patient Lilith Arthur (Seberg).
After engineering the suicide of another patient (Fonda) out of jealousy for his crush on Lilith, Bruce presents himself for psychiatric help to his superiors.
I recently made a post about the meaning of Lilith (#9115):
Lilith is believed to have originated as a female Mesopotamian storm demon associated with wind and was thought to be a bearer of disease, illness, and death.
In modern Luciferianism, Lilith is considered a consort of Lucifer and is identified with the figure of Babalon.
She is said to come from the mud and dust, and is known as the Queen of the Succubi.
When she and Lucifer mate, they form an androgynous being called "Baphomet" or the "Goat of Mendes") (Wikipedia)
Jean Seberg also reminds me of Mia Farrow in "Rosemary's Baby" (1968) and her famous short haircut.
Although Jean was first, "Breatless" was filmed in 1959 and she wore that short haircut already back then...
In "Rosemary's Baby", Rosemary's husband sells his soul for fame. Neighbours and people around her are Satan worshippers and it turns out that the father of her son is not her husband but Satan, and her son is destined to take his place at his father's side to rule in Hell, and hold dominion over the earth.
The movie was filmed partially on location at The Dakota, in New York City.
The same building where John Lennon lived and also the location of his murder in 1980.
When the movie starts Rosemary has longer hair but during her pregnancy it's cut. Rosemary goes from being an innocent-looking, happy young girl to a ghastly, unhappy, very sick looking woman = the mother of the Antichrist.
