Absolute power corrupts absolutely in Caligula: The Ultimate Cut, an extensive reconstruction of the notorious 1980 spectacle. Shadowed by the murder of his family, Caligula (Malcolm McDowell) eliminates his devious adoptive grandfather (Peter O’Toole), and seizes control of the Roman Empire alongside his wife Caesonia (Helen Mirren) before descending into a spiral of depravity, destruction, and madness.
