Cannibali, the third feature film by Liliana Cavani, starring a trio of excellent actors (Pierre Clementi, Britt Ekland and Tomas Milian), is a modern reinterpretation of Sophocles' tragedy, made during the protest years of 1967-69. A film that stands out for its visionary intelligence, in the context of Italian "political" cinema.
