Ewan McGregor

Scottish actor Ewan McGregor's career flourished in the 1990s with roles in college-crowd cult favorite "Trainspotting" and as a young Obi Wan-Kenobi in the "Star Wars" prequel trilogy. But through it all, his passion for motorcycles never wavered. His epic globetrotting trips with best friend Charley Boorman turned into a sort of second career for McGregor: motorcycle philanthropist. Along his journey, McGregor and Boorman made several charitable visits to third-world orphanages, villages and schools. McGregor eventually became a UNICEF ambassador, and his motorcycle rides became the basis for two documentary series and a bestselling book.
