Exclusively available to watch instantly from 20 November, Intelligence Squared brings the ultimate clash of civilisations to Curzon Home Cinema: Greece vs Rome. Following the day after the event’s sold-out performance at Westminster’s Central Hall, this unique filmed debate brings together the ultimate clash of intellectual titans. Boris Johnson, Mayor of London and ardent classicist, makes the case for Greece; while Mary Beard, Professor of Classics at Cambridge and redoubtable media star, champions Rome. Some say that if Mary Beard had been in charge, the Roman Empire would never have fallen. Others say Boris is soon to be the Pericles of Downing Street. Who gets your vote?
