McGregor first came to prominence in 'Shallow Grave', the debut feature by Danny Boyle in which he starred with Kerry Fox and Christopher Eccleston. He went on to appear in 'Blue Juice', 'Emma', 'Brassed Off' and 'The Pillow Book', but it was as Renton in Danny Boyle's 'Trainspotting' that McGregor became a household name in a role which captured the imagination of teenagers worldwide. He went on to star in 'The Serpent's Kiss', 'Nightwatch' and 'A Life Less Ordinary' again directed by Boyle, 'Rogue Trader, 'The Eye of the Beholder', 'The Rise and Fall of Little Voice', 'Velvet Goldmine' and George Lucas' hotly anticipated 'Star Wars' prequel in which he plays the young Obi Wan Kenobi.

He recently appeared on stage in 'Little Malcolm and His Struggle Against the Eunuchs', directed by Denis Lawson, to great acclaim.
