Explorer, a portrait of Sir Ranulph Fiennes, is a documentary that peels back the layers of Sir Ranulph's life to go beyond all of his record-breaking achievements and reveal the man behind the myth. Sir Ranulph Fiennes is credited with the sensational title of being the World's Greatest Living Explorer. Amongst his extraordinary achievements, he was the first to circumnavigate the world from pole to pole, crossed the Antarctic on foot, broke countless world records and discovered a lost city in Arabia. He has traveled to the most dangerous places on Earth, lost half his fingers to frostbite, raised millions of pounds for charity and was nearly cast as James Bond (and yes, he does happen to be a cousin to Ralph and Joseph). But who is the man who prefers to be known as just "Ran"?
