A flawed but interesting piece, Anna M comes out of the Fatal Attraction school of thrillers.

Anna (Isabelle Carre) works as a bookbinder at her local general library. She lives with her mother and being a lonely sort, yearns for the attention of a man. She finds one through rather extreme means. She causes herself to be involved in an accident, in order to meet a doctor at the local hospital and when Dr Zanevsky (Gilbert Melki) says purely in a way a doctor would say to a patient, 'I'll need to see you again', Anna very much takes him at his word, feeling this is the sign of romance, even though the doctor is happily involved in a relationship.

What will follow is an ever-escalating liaison as Dr Zanevsky first is happy to bump into Anna and have a coffee with her but he's less impressed once she starts laying in wait for him at his workplace and outside his apartment and sending letters daily to his letterbox.

For director Michel Spinosa, this film was a chance to explore the lesser-known condition of Erotomania, a serious psychosis in which erotomaniacs who we understand are often women, go through a process of infatuation which is a certified medical condition.

For sure, this is a worthwhile condition to explore in a feature film and Anna M is an interesting study of it. Sadly, it's let down only by a plot which gets ever more unlikely.

Dr Zanevsky can easily see early on that Anna needs help. But mysteriously he turns to an unbelievably unhelpful policeman for help and for reasons that only suit the director and screenwriter's plot, he doesn't look for a colleague on his doorstep at the hospital, medically trained to help Anna.

Instead, we need to see Anna showing ever-increasing signs of madly thinking they're an item and Zanevsky's own relationship suffering under the strain of her doing that. As a bunny boiler, Anna is medically unstable in a medically unhinged kind of a way, and even though you don't quite see her boiling a pet rabbit in a Fatal Attraction kind of a way, there are some seriously uncomfortable scenes when she's medically sick and physically harming children she's been supposed to be caring for.

Weirdly, her mother seems blind to the signs even though her daughter's suffered from this before, as does the policeman despite all the signs of Anna's harassment and infatuation.

In spite of flaws in the story, Anna M is a reasonable attempt to explain this form of medically advanced infatuation. The casting is good, and Gilbert Melki and Isabelle Carre as the doctor and his obsessive are played well, making for a fairly memorable film.
