What does it take to bring Ewan McGregor to the small screen? “Something special,” he recently told me. He was referring to FX’s Fargo, which begins its third season on Wednesday. McGregor’s name is synonymous with the big screen, thanks to hit films and franchises like Trainspotting, Moulin Rouge and the three Star Wars prequels (where he took on the role of a young Obi Wan Kenobi, the Jedi master famously portrayed in the first three movies by Sir Alec Guinness). Most recently he gave voice to Lumiere in Disney’s live action version of Beauty and the Beast, but the lure of television was something the 46-year-old had been eyeing for some time. Playing the lead roles in Fargo – brothers Emmett and Raymond Stussy -- did the trick.
