This is part of the She’s So Giallo (Women of 1970s Italian Thrillers) season at the Barbican curated by Josh Saco, aka Cigarette Burns Cinema. You can find all the details here.
Here is the Barbican introduction:
Philippe Leroy stars as Dr Sayer, a rich philanthropist who has a dark secret to hide in Piero Schivazappa’s pop art thriller. When Maria (Dagmar Lassander), a journalist, drops by Sayer's mansion to pick up some documents, she soon finds herself victim to his unpleasant and degrading games. But the tables are turned as Maria subverts the doctor's game and becomes the manipulator.
We're delighted to have Virginie Sélavy, editor of Electric Sheep Magazine, introduce this screening.
Here (and above) is the trailer.
