Prince, Son and Heir: Charles At 70

With exclusive access to The Prince of Wales in his 70th birthday year, this intimate and revealing film follows the British heir to the throne over the course of a year, both at work and behind the scenes, at home and abroad. Film-maker John Bridcut also speaks to those who know him best, his wife The Duchess of Cornwall, and his sons, Prince William and Prince Harry, who both speak about their upbringing as teenagers. Prince Charles's 70th birthday marked half a century of involvement in public affairs. He has championed issues that once were unfamiliar but are now mainstream - such as global warming and youth opportunity. The longest-serving heir to the throne discusses his ongoing charitable work and looks ahead to his future role as monarch.
