Trivia: After the execution of Charles I / Alec Guiness, Oliver Cromwell / Richard Harris returns to his home. Sitting by the fire, he is consoled by his wife: he can now put the cares and worries of war and politics behind him, and enjoy a quiet life as a country gentleman. This cosy domesticity is rudely interrupted when some of his old colleagues arrive to tell him tell him that he is now needed to run the country. He protests that, as a country gentleman he would be unfit for such a role, but he reluctantly assumes power. In fact, by the time of Charles I's execution Oliver Cromwell was one of the most powerful political figures and military commanders in Britain, and actively continued commanding armies in Ireland, Scotland and England, and involving himself in government. Although rejecting a suggestion that he should be crowned king (after much deliberation), he was quite willing to take the title of 'Lord Protector' and govern England, Scotland, Ireland and Wales until his death in 1658.
