An American biographical adventure; A story about a man who journeys into the Amazon at the dawn of the 20th century and discovers evidence of a previously unknown, advanced civilization that may have once inhabited the region. He was aiming for a city he called 'Z'. It's a film which hearkens back to classic exploration epics of the mid 20th Century. Charlie Hunnam gives a well measured performance as the British geographer, Army Major, and explorer Percy Fawcett. The film centres on passion and determination and obsession and escape but also the losses suffered by leaving the home - his growing family and dutiful wife - in service of fantastical dreams. It is a biopic by numbers and this is a troublesome area because Fawcett and his story have many critics. Nonetheless it is a stately adventure despite the slow pacing.
