In a statement prior to the ceremony, Polanski said he would not attend because activists were threatening him with “a public lynching.” Following his win, several famous actresses in the French community came to his defense including Brigitte Bardot and Franny Ardant, the latter of whom said, among other things, “Long live freedom.” Many inside the ceremony, however, did not share those sentiments including host Florence Foresti who reportedly took several shots at the movie while on stage and even told the audience not to applaud for it. She later posted an Instagram Story that just said “Disgusting”.
