Gialli and erotic horror films
Neri, the bombshell, was also much in demand for erotic giallo thrillers, horror, and sexploitation films. She was in Jess Franco's box office hit 99 Women (1969), one of the first women in prison films, and Top Sensation (The Seducers) (1969) opposite Edwige Fenech. In 1972 she played Farley Granger's wife in Amuck!. Granger plays a wealthy author, and the couple engages in kinky sex games with his beautiful secretary (Barbara Bouchet) while also playing af dangerous psychological game of life and death. Also in 1972, Neri played the lead role in the erotic horror flick Lucifera: Demon Lover.
Bouchet and Neri would team up in 1972 in another movie combining sex with horror, Casa d’appuntamento (French Sex Murders). A jewel thief is accused of murdering a prostitute but is decapitated in a motorcycle accident prior to the trial. When those involved in the trial start dying off, everyone wonders if the dead man has come back to exact his revenge.
Perhaps Neri's best-known films are from the horror genre. Credited as Sara Bay, she played Tania Frankenstein, the daughter of the monster's creator, in 1971's Lady Frankenstein. Tania was willing to take her father's work to new – and frightening – levels. It is considered a B movie classic.
In 1973, she starred in The Devil's Wedding Night as Lady Dracula, a vampire who uses Dracula's ring to lure young virgins to her home so she can murder them and bathe in their blood (à la the medieval Countess Elizabeth Báthory). In Italy, it was released as Il Plenilunio dell Vergini (Full Moon of the Virgins).
