L'estate stregata (1988)

Authors Lord Byron, Mary Shelley and Percy Shelley get together for some philosophical discussions, but the situation soon deteriorates into mind games, drugs, and sex. It is a fictionalization of the summer that Lord Byron and the Shelleys, together with Lord Byron's ex-lover Claire Clairmont and his Doctor John Polidori, spent in the isolated Villa Diodati by Lake Geneva. It is there they devise a contest to adduce the best horror story to kill the dullness of summer. It is also there that one of the world's most famous books was given life—Mary Shelley's Frankenstein.
