Shakespeare's Julius Caesar is a play that upholds liberty against tyranny. But what is tyranny? And who decides? Shakespeare doesn't make it simple. In order to preserve the freedom of the Roman Republic, Julius Caesar, an "over-mighty" leader, is assassinated by Roman Senators led by Caesar's friend Brutus. Caesar wanted to become an emperor. Is Brutus a traitor or a great hero and defender of liberty? Brian Cox explores how Julius Caesar is Shakespeare's "American" play, showing how easy it is for a "free" republic to fall into corruption. More than that, the play challenges us to think about who or what to trust and what values we want to live by - and to look inside and wonder how well we even know ourselves.
