Famed for films "Rosemary's Baby", "Chinatown" and "The Pianist", the 86-year-old launched his new film "I accuse", which tells the story of a Jewish officer imprisoned on false evidence.
Monnier, now 62, believes Polanski has used the plot to mirror his own case from 1977.
"Is it tenable, under the pretext of a film, under the cover of history, to hear the person who has marked you for life to say 'I accuse', while preventing you – the victim – to accuse him?" Monnier is reported as saying.
She also described her alleged ordeal as a "traumatic memory" and called rape "a time bomb".
According to the Daily Mail, Monnier endured guilt for decades but was too afraid to go to authorities.
Polanski, who was married to Sharon Tate when she was murdered by members of Charles Manson's cult, has "firmly denies all accusations of rape," according to his lawyer.
In France, a 20-year statute of limitations means Polanski cannot be prosecuted for a crime that allegedly took place in 1975.
