Born in Crieff, Scotland, drama school drop-out McGregor has been working steadily on the stage, in Hollywood and indie arthouse flicks ever since he wowed with his break-out role as a junkie in 1996's Trainspotting.
He's proved there's no part he can't tackle, portraying everything from a glam rock star to a priest and, of course, a Jedi Knight.
To salute Ewan on his special day, WENN has opened up the archives and dug up 10 facts about his life.

- Before playing Obi-Wan Kenobi, McGregor was already a Star Wars fan - his uncle, actor/director Denis Lawson, played an X-wing pilot in all three original Star Wars movies.
