The Roman Emperor Caligula, also known as Gaius, exploring his brief but brutal reign from AD 37 to 41, highlighting his initial popular policies - cutting taxes and pardoning exiles - which were followed by a descent into madness and tyrannical behaviour. This documentary delves into the historical context of his rule and the events surrounding his assassination.

Tsar Ivan IV Vasilyevich - Ivan the Terrible - was the first grand prince of Moscow from 1533 to 1547 and later ruled as the "Tsar of all Russia" until his death in 1584. Back in the 16th Century when the suffix Terrible was first bestowed on Ivan, it meant ‘awe-inspiring', ‘powerful' and ‘formidable'. By the end of his reign, most of his subjects probably felt the word as we understand it today was more apt.
