Just googled for the story. This is from
www.cinematical.com
This film is based on a true story.
It seems like an important thing for us to be aware of right off
the bat, because very little in the film to follow resembles any
kind of true life, at least as most of us know it.
The Exorcism of Emily Rose is ostensibly based on the story of
Anneliese Michel, a German college student who believed she was
possessed by multiple demons, including Lucifer, Nero, Judas
Iscariot, and Adolf Hitler. In 1975, several years after Michel had
started suffering from extreme seizures and exhibiting generally
unexplained behavior (compulsions to self-mutilate and publicly
urinate; the ability to speak languages Michel had never learned),
the Catholic church gave her priest permission to perform an
exorcism. Various traditional Church rituals were performed at
least once a week for ten months, until, in July of 1976, Michel
died of starvation (she had claimed for months that the demons
would not allow her to eat). Annelieses parents, and the priest
who officiated Michels exorcism, were brought to trial on charges
of manslaughter, and sentenced to six months in prison. Michel's
grave has since become an ad-hoc holy site for devout believers,
even though the Church later issued a statement denying that Michel
had ever been possessed......
